Summary: The PlaceholderObjectFile has an assert in SetLoadAddress that fires if "m_base == value" is not true. To avoid this, we create check that the base address matches, and if it doesn't we clear the module that was found using the UUID so that we create a new PlaceholderObjectFile. Added a test to cover this issue.

Most of the secondary Makefiles we have are just a couple variable
definitions and then an include of Makefile.rules. This patch removes
most of the secondary Makefiles and replaces them with a direct
invocation of Makefile.rules in the main Makefile. The specificities
of each sub-build are listed right there on the recursive $(MAKE)
call. All the variables that matter are being passed automagically by
make as they have been passed on the command line. The only things you
need to specify are the variables customizating the Makefile.rules
logic for each image.
This patch also removes most of the clean logic from those Makefiles
and from Makefile.rules. The clean rule is not required anymore now
that we run the testsuite in a separate build directory that is wiped
with each run. The patch leaves a very crude version of clean in
Makefile.rules which removes everything inside of $(BUILDDIR). It does
this only when the $(BUILDDIR) looks like a sub-directory of our
standard testsuite build directory to be extra safe.

Summary:
As we figured out in D67803, importing declarations from a temporary ASTContext that were originally from a persistent ASTContext
causes a bunch of duplicated declarations where we end up having declarations in the target AST that have no associated ASTImporter that
can complete them.
I haven't figured out how/if we can solve this in the current way we do things in LLDB, but in the modern-type-lookup this is solvable
as we have a saner architecture with the ExternalASTMerger. As we can (hopefully) make modern-type-lookup the default mode in the future,
I would say we try fixing this issue here. As we don't use the hack that was reinstated in D67803 during modern-type-lookup, the test case for this
is essentially just printing any kind of container in `std::` as we would otherwise run into the issue that required a hack like D67803.
What this patch is doing in essence is that instead of importing a declaration from a temporary ASTContext, we instead check if the
declaration originally came from a persistent ASTContext (e.g. the debug information) and we directly import from there. The ExternalASTMerger
is already connected with ASTImporters to these different sources, so this patch is essentially just two parts:
1. Mark our temporary ASTContext/ImporterSource as temporary when we import from the expression AST.
2. If the ExternalASTMerger sees we import from the expression AST, instead of trying to import these temporary declarations, check if we
can instead import from the persistent ASTContext that is already connected. This ensures that all records from the persistent source actually
come from the persistent source and are minimally imported in a way that allows them to be completed later on in the target AST.
The next step is to run the ASTImporter for these temporary expressions with the MinimalImport mode disabled, but that's a follow up patch.
This patch fixes most test failures with modern-type-lookup enabled by default (down to 73 failing tests, which includes the 22 import-std-module tests
which need special treatment).

A lot of commands are made up of CommandObjectMultiword with

The story so far: LLDB's modern type lookup mode has no (as in, 0%) test
coverage. It was supposed to be tested by hardcoding the default to 'true' and then running
the normal LLDB tests, but to my knowledge no one is doing that. As a around 130 tests
seem to fail with this mode enabled, we also can't just enable it globally for now.
As we touch the surrounding code all the time and also want to refactor parts of it, we
should be a bit more ambitious with our testing efforts.
So this patch adds two basic tests that enable this mode and do some
basic expression parsing which should hopefully be basic enough to not
break anywhere but still lets us know if this mode works at all (i.e. setting up the
ExternalASTMerger in LLDB, using its basic import functionality to move declarations
around and do some lookups).

r366433 broke support for the system debugserver. Although the change
was well-intended, it (presumably) unintentionally removed the logic to
copy over the debugserver. As a result, even with
LLDB_USE_SYSTEM_DEBUGSERVER enabled, we ended up building, signing and
using the just-built debugserver.
This patch partially recovers the old behavior: when
LLDB_USE_SYSTEM_DEBUGSERVER is set we don't build debugserver and just
copy over the system one.

Summary:
In D61333 we dropped some code from ClangASTSource that checks if imported declarations
ended up in the right DeclContext. While this code wasn't tested by the test suite (or better, it was hit
by the test suite but we didn't have any checks that were affected) and the code seems pointless
(as usually Decls should end up in the right DeclContext), it actually broke the data formatters in LLDB
and causes a bunch of obscure bugs where structs suddenly miss all their members. The first report we got about
this was that printing a std::map doesn't work anymore when simply doing "expr m" (m is the std::map).
This patch reverts D61333 partly and reintroduces the check in a more stricter way (we actually check now that
we *move* the Decl and it is in a single DeclContext). This should fix all the problems we currently have until
we figure out how to properly fix the underlying issues. I changed the order of some std::map formatter tests
which is currently the most reliable way to test this problem (it's a tricky setup, see description below).
Fixes rdar://55502701 and rdar://55129537
--------------------------------------
Some more explanation what is actually going on and what is going wrong:
The situation we have is that if we have a `std::map m` and do a `expr m`, we end up seeing an empty map
(even if `m` has elements). The reason for this is that our data formatter sees that std::pair<int, int> has no
members. However, `frame var m` works just fine (and fixes all following `expr m` calls).
The reason for why `expr` breaks std::map is that we actually copy the std::map nodes in two steps in the
three ASTContexts that are involved: The debug information ASTContext (D-AST), the expression ASTContext
we created for the current expression (E-AST) and the persistent ASTContext we use for our $variables (P-AST).
When doing `expr m` we do a minimal import of `std::map` from D-AST to E-AST just do the type checking/codegen.
This copies std::map itself and does a minimal.import of `std::pair<int, int>` (that is, we don't actually import
the `first` and `second` members as we don't need them for anything). After the expression is done, we take
the expression result and copy it from E-AST to P-AST. This imports the E-AST's `std::pair` into P-AST which still
has no `first` and `second` as they are still undeserialized. Once we are in P-AST, the data formatter tries to
inspect `std::map` (and also `std::pair` as that's what the elements are) and it asks for the `std::pair` members.
We see that `std::pair` has undeserialized members and go to the ExternalASTSource to ask for them. However,
P-ASTs ExternalASTSource points to D-AST (and not E-AST, which `std::pair` came from). It can't point to E-AST
as that is only temporary and already gone (and also doesn't actually contain all decls we have in P-AST).
So we go to D-AST to get the `std::pair` members. The ASTImporter is asked to copy over `std::pair` members
and first checks if `std::pair` is already in P-AST. However, it only finds the std::pair we got from E-AST, so it
can't use it's map of already imported declarations and does a comparison between the `std::pair` decls we have
Because the ASTImporter thinks they are different declarations, it creates a second `std::pair` and fills in the
members `first` and `second` into the second `std::pair`. However, the data formatter is looking at the first
`std::pair` which still has no members as they are in the other decl. Now we pretend we have no declarations
and just print an empty map as a fallback.
The hack we had before fixed this issue by moving `first` and `second` to the first declaration which makes
the formatters happy as they can now see the members in the DeclContext they are querying.
Obviously this is a temporary patch until we get a real fix but I'm not sure what's the best way to fix this.
Implementing that the ClassTemplateSpecializationDecl actually understands that the two std::pair's are the same
decl fixes the issue, but this doesn't fix the bug for all declarations. My preferred solution would be to
complete all declarations in E-AST before they get moved to P-AST (as we anyway have to do this from what I can
tell), but that might have unintended side-effects and not sure what's the best way to implement this.
