Shaurya Gupta 0d26d6f887 [clangd] Fixed toHalfOpenFileRange
Summary:
- Fixed toHalfOpenFileRange to work for macros as well as template
instantiations
- Added unit tests

Breaking test case for older version of toHalfOpenFileRange:
\# define FOO(X) X++
int a = 1;
int b = FOO(a);
toHalfOpenFileRange for the sourceRange of VarDecl for b returned the
wrong Range.

Sam McCall 0f7146db9b [clangd] Prioritize indexing of files that share a basename with the open file.
Summary:
In practice, opening Foo.h will still often result in Foo.cpp making the
second index build instead of the first, as the rebuild policy doesn't
know to wait.

Nathan Ridge 5b9484e559 [clangd] Implement typeHierarchy/resolve for subtypes

This allows the client to resolve subtypes one level at a time.

For supertypes, this is not necessary, because we eagerly compute

Sam McCall 9470142ca5 [clangd] Implementation of auto type expansion.
Add a tweak for clangd to replace an auto keyword to the deduced type.

This way a user can declare something with auto and then have the
IDE/clangd replace auto with whatever type clangd thinks it is. In case
of long/complext types this makes is reduces writing effort for the
user.

The functionality is similar to the hover over the auto keyword.

Example (from the header):

```
/// Before:
///    auto x = Something();
///    ^^^^
/// After:
///    MyClass x = Something();
///    ^^^^^^^
```

Don Hinton 43d75f9778 Recommit "[CommandLine] Remove OptionCategory and SubCommand caches from the Option class."
Previously reverted in 364141 due to buildbot breakage, and fixed here
by making GeneralCategory global a ManagedStatic.

Summary:
This change processes `OptionCategory`s and `SubCommand`s as they
are seen instead of caching them in the Option class and processing
them later.  Doing so simplifies the work needed to be done by the Global
parser and significantly reduces the size of the Option class to a mere 64
bytes.

Removing  the `OptionCategory` cache saved 24 bytes, and removing
the `SubCommand` cache saved an additional 48 bytes, for a total of a
72 byte reduction.

Sam McCall 2f760c44e6 [clangd] Rewrite of logic to rebuild the background index serving structures.
Summary:
Previously it was rebuilding every 5s by default, which was much too frequent
in the long run - the goal was to provide an early build. There were also some
bugs. There were also some bugs, and a dedicated thread was used in production
but not tested.

 - rebuilds are triggered by #TUs built, rather than time. This should scale
   more sensibly to fast vs slow machines.
 - there are two separate indexed-TU thresholds to trigger index build: 5 TUs
   for the first build, 100 for subsequent rebuilds.
 - rebuild is always done on the regular indexing threads, and is affected by
   blockUntilIdle. This means unit/lit tests run the production configuration.
 - fixed a bug where we'd rebuild after attempting to load shards, even if there
   were no shards.
 - the BackgroundIndexTests don't really test the subtleties of the rebuild
   policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough
   to pass the tests). Instead, we expose the rebuilder as a separate class and
   have fine-grained tests for it.

Sam McCall 674d8a947c [clangd] Use xxhash instead of SHA1 for background index file digests.
Summary:
Currently SHA1 is about 10% of our CPU, this patch reduces it to ~1%.

xxhash is a well-defined (stable) non-cryptographic hash optimized for
fast checksums (like crc32).
Collisions shouldn't be a problem, despite the reduced length:
 - for actual file content (used to invalidate bg index shards), there
   are only two versions that can collide (new shard and old shard).
 - for file paths in bg index shard filenames, we would need 2^32 files
   with the same filename to expect a collision. Imperfect hashing may
   reduce this a bit but it's well beyond what's plausible.

This will invalidate shards on disk (as usual; I bumped the version),
but this time the filenames are changing so the old files will stick
around :-( So this is more expensive than the usual bump, but would be
good to land before the v9 branch when everyone will start using bg index.
