Summary: Added a class for diffing highlightings and removing duplicate lines. Integrated into the highlighting generation flow. Only works correctly if all tokens are on a single line. Also returns empty lines if the IDE should remove previous highlightings on a line.

Summary:
Whitespace and comments are a clear bugfix: selecting some
comments/space near a statement doesn't mean you're selecting the
surrounding block.
Semicolons are less obvious, but for similar reasons: these tokens
aren't actually claimed by any AST node (usually), so an AST-based model
like SelectionTree shouldn't take them into account.
Callers may still sometimes care about semis of course:
- when the selection is an expr with a non-expr parent, selection of
the semicolon indicates intent to select the statement.
- when a statement with a trailing semi is selected, we need to know
its range to ensure it can be removed.
SelectionTree may or may not play a role here, but these are separate questions
from its core function of describing which AST nodes were selected.
The mechanism here is the TokenBuffer from syntax-trees. We use it in a
fairly low-level way (just to get boundaries of raw spelled tokens). The
actual mapping of AST nodes to coordinates continues to use the (fairly
mature) SourceLocation based logic. TokenBuffer/Syntax trees
don't currently offer an alternative to getFileRange(), I think.

Sprinkled some #ifndef NDEBUG in Selection.cpp to make
it possible to build with NDEBUG defined.
The problem was introduced in rL366698 when using dlog
for some debug printouts. The dlog macro expands to
DEBUG_WITH_TYPE, which isn't using it's arguments in
optimized builds (when NDEBUG is defined).

Summary:
These aren't formally subexpressions in C++, in this case + is left-associative.
However informally +, *, etc are usually (mathematically) associative and users
consider these subexpressions.
We detect these and in simple cases support extracting the partial expression.
As well as builtin associative operators, we assume that overloads of them
are associative and support those too.

This simplifies various workflows, particularly in debugging/development.
e.g. editors will tend to propagate flags, so you can run
`env CLANGD_FLAGS=-input-mirror-file=/tmp/mirror vim foo.cc` rather than
change the configuration in a persistent way.
(This also gives us a generic lever when we don't know how to customize
the flags in some particular LSP client).
While here, add a test for this and other startup logging, and fix a
couple of direct writes to errs() that should have been logs.

Summary:
Previously TranslationUnitDecl would never be selected.
This means root() is never null, and returns a reference.
commonAncestor() is in principle never null also, but returning TUDecl
here requires tweaks to be careful not to traverse it (this was already
possible when selecting multiple top-level decls, and there are associated bugs!)
Instead, never allow commonAncestor() to return TUDecl, return null instead.

Summary:
SelectionTree is a RecursiveASTVisitor which processes getSourceRange() for
every node. This is a lot of surface area with the AST, as getSourceRange()
is specialized for *many* node types.
And the resulting SelectionTree depends on the source ranges of many
visited nodes, and the order of traversal.
Put together, this means we really need a traversal log to debug when we
get an unexpected SelectionTree. I've built this ad-hoc a few times, now
it's time to check it in.

Summary:
Changes persistance logic to store shards at the directory of closest
CDB. Previously we were storing all shards to directory of the CDB that
triggered indexing, it had its downsides.
For example, if you had two TUs coming from a different CDB but depending on the
same header foo.h, we will store the foo.h only for the first CDB, and it would
be missing for the second and we would never persist it since it was actually
present in the memory and persisted before.
This patch still stores only a single copy of a shard, but makes the directory a
function of the file name. So that the shard place will be unique even with
multiple CDBs accessing the file. This directory is determined as the first
directory containing a CDB in the file's parent directories, if no such
directory exists we make use of the home directory.

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();
/// ^^^^^^^

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.

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.
