With ObjCPropertyDecl, ASTNode.OrigD can be a ObjCPropertyImplDecl
which is not a NamedDecl, leading to a crash since the code
incorrectly assumes ASTNode.OrigD will always be a NamedDecl.

Summary:
Some projects make use of clang plugins when building, but clangd is
not aware of those plugins therefore can't work with the same compile command
arguments.
There were multiple places clangd performed commandline manipulations,
this one also moves them all into OverlayCDB.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Files without any symbols were never marked as updated during indexing, which resulted in failure while writing shards for these files.

Summary:
There was a chance that multiple clangd instances could try to write
same shard, in which case we would get a malformed file most likely. This patch
changes the writing mechanism to first write to a temporary file and then rename
it to fit real destination. Which is guaranteed to be atomic by POSIX.

Summary:
We'll soon have tasks pending for reading shards from disk, we want
them to have normal priority. Because:
- They are not CPU intensive, mostly IO bound.
- Give a good coverage for the project at startup, therefore it is worth
spending some cycles.
- We have only one task per whole CDB rather than one task per file.

Summary:
Currently, there's no way of knowing about header files
using compilation database, since it doesn't contain header files as entries.
Using this information, restoring from cache using compile commands becomes
possible instead of doing directory traversal. Also, we can issue indexing
actions for out-of-date headers even if source files depending on them haven't
changed.

Summary:
Ownership and configuration:
The auto-index (background index) is maintained by ClangdServer, like Dynamic.
(This means ClangdServer will be able to enqueue preamble indexing in future).
For now it's enabled by a simple boolean flag in ClangdServer::Options, but
we probably want to eventually allow injecting the storage strategy.
New 'sync' command:
In order to meaningfully test the integration (not just unit-test components)
we need a way for tests to ensure the asynchronous index reads/writes occur
before a certain point.
Because these tests and assertions are few, I think exposing an explicit "sync"
command for use in tests is simpler than allowing threading to be completely
disabled in the background index (as we do for TUScheduler).
Bugs:
I fixed a couple of trivial bugs I found while testing, but there's one I can't.
JSONCompilationDatabase::getAllFiles() may return relative paths, and currently
we trigger an assertion that assumes they are absolute.
There's no efficient way to resolve them (you have to retrieve the corresponding
command and then resolve against its directory property). In general I think
this behavior is broken and we should fix it in JSONCompilationDatabase and
require CompilationDatabase::getAllFiles() to be absolute.

Summary:
Instead of receiving compilation commands, auto-index is triggered by just
filenames to reindex, and gets commands from the global comp DB internally.
This has advantages:
- more of the work can be done asynchronously (fetching compilation commands
upfront can be slow for large CDBs)
- we get access to the CDB which can be used to retrieve interpolated commands
for headers (useful in some cases where the original TU goes away)
- fits nicely with the filename-only change observation from r347297
The interface to GlobalCompilationDatabase gets extended: when retrieving a
compile command, the GCDB can optionally report the project the file belongs to.
This naturally fits together with getCompileCommand: it's hard to implement one
without the other. But because most callers don't care, I've ended up with an
awkward optional-out-param-in-virtual method pattern - maybe there's a better
one.
This is the main missing integration point between ClangdServer and
BackgroundIndex, after this we should be able to add an auto-index flag.

llvm-svn: 347538
Summary:
Instead of passing around a list of supported URI schemes in clangd, we
expose an interface to convert a path to URI using any compatible scheme
that has been registered. It favors customized schemes and falls
back to "file" when no other scheme works.
Changes in this patch are:
- URI::create(AbsPath, URISchemes) -> URI::create(AbsPath). The new API finds a
compatible scheme from the registry.
- Remove URISchemes option everywhere (ClangdServer, SymbolCollecter, FileIndex etc).
- Unit tests will use "unittest" by default.
- Move "test" scheme from ClangdLSPServer to ClangdMain.cpp, and only
register the test scheme when lit-test or enable-lit-scheme is set.
(The new flag is added to make lit protocol.test work; I wonder if there
is alternative here.)
