Vedant Kumar e62b54ed2a Revert "[lldb][cmake] Remove libclang as an lldbBase dependency (NFCI)"
This reverts commit r279296. Including LLDBDependencies breaks the
netbsd lldb bot because it exposes LLDB_USED_LIBS, which causes
lldb_link_common_libs to run to completion in unintended sites, which
results in a malformed call to target_link_libraries.

Thanks to Chris Bieneman for figuring this out!

Vedant Kumar 181f924beb [lldb][cmake] Remove libclang as an lldbBase dependency (NFCI)
It's pulling in all kinds of things it doesn't need (e.g, clang-tidy!).

Eliminating this dependency removes 1056 dependencies from the
'CommandObjectFrame.cpp.o' target and 454 dependencies from the 'lldb'
target. On my machine, this shaves 7 minutes off of a clean build of
lldb.

Thanks to Zachary Turner for pointing out some issues with an earlier
version of this patch!

Zachary Turner 74e08ca05c Add support for reading line tables from PDB files.
PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.

Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows.  This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.

This patch only adds support for line tables.  It does not return
information about functions, types, global variables, or anything
else.  This functionality will be added in a followup patch.

Pavel Labath 48003e721e Fix linking with LLVM_LINK_LLVM_DYLIB=ON
Linking with LLVM shared libraries currently produces linker errors.  This works around the issue
(pr24953) by disabling linking with llvm so for lldb libraries.

Todd Fiala d6f840609b cmake: provide flag that enables 'log enable --stack' to provide useful file/function info on POSIX systems
Adding the following flag to a cmake line:
-DLLDB_EXPORT_ALL_SYMBOLS=TRUE

will cause all symbols to be exported from liblldb.  This enables the llvm
backtrace mechanism to see and report backtrace symbols properly when using
(lldb) log enable --stack ...

Prior to this change, only the SB API symbols would show up on Linux and other
systems that use a public-symbols-based backtrace lookup mechanism.

log enable --stack ... is a very handy, quick way to understand the flow
of how some log lines are getting hit within lldb without having to hook
up a top-level debugger over your current debug session.

Andrew Wilkins 7175f16cdb [lldb] Enable building with Cmake/BUILD_SHARED_LIBS
Summary:
Several changes to fix CMake builds of LLDB with the
BUILD_SHARED_LIBS setting on.

- Force all internal libraries to be built STATIC.
- Add additional library dependencies (pthread, dl,
  runtimedyld).
- modify finalisation of SWIG wrapper to symlink the
  "lib" dir into python/site-packages, so _lldb.so's
  RPATH resolves.

Test Plan: Verified one test case with "dotest.py".

A previous attempt to make the unit tests link properly on
Linux broke it for Windows.  This patch fixes it for both platforms.

Zachary Turner 44a14d95c2 [CMake] Refactor LLDB main CMake file.
The existing state of affairs was getting a little unwieldy.

All of LLDB's utility functions and initial configuration was in
the root CMake file.  I split this up into 3 separate files and
moved them to relevant subfolders under cmake/modules.

Also, I deleted the add_lldb_definitions() function.  It seemed
to be somewhat useless and did not serve any real purpose that
I was able to figure out.
