Benjamin Kramer a3d823336a [include-fixer] Rename XrefsDB to SymbolIndex.
It's not really containing xrefs so the name didn't fit. No functional change.

Benjamin Kramer 79acc976ea [include-fixer] Always ignore SFINAE contexts.
This could lead to spurious includes being added for identifiers that
are supposed to be not available.

Benjamin Kramer 3246fba975 [include-fixer] Also output the location where we found an unknown identifier.
For debugging only, makes it a bit easier when there are queries coming
out of headers.

Haojian Wu 075ba119b2 [find-all-symbols] Save relative file path for each symbol.
Summary:
The HeaderSearch::suggestPathToFileForDiagnostics used in include-fixer
doesn't work well with absolute file path, it assumes a relative file
path based on header searching path.

So saving relative file path to make include-fixer get the most
appropriate header path.

Haojian Wu 1a352d564f [find-all-symbols] Slim SymbolInfo.
Summary:
SymbolInfo has some optional fields, which is a bad-smell
implementation. For now, we

* remove the optional field since we don't need them (we can probably
  add them back if we actually need them in the future)
* make SymbolInfo to be a class.

By this change, the code is more simplified.

Benjamin Kramer ad93500c52 [include-fixer] Work around partial names in both directions.
We already handled the case where we had a nested name specifier where
parts from the beginning don't get a callback, also handle the case
where the end doesn't get a callback. This happens with function calls
in unknown namespaces.

The way we do this for now based on character data is a bit of a hack, we
may need to refine this later or fix clang to produce different callbacks.

Benjamin Kramer c3459a5002 [include-fixer] For now, only add the first suggested include.
We used a std::set which made the picked include somewhat random (well,
lexicographically sorted). Make the behavior more consistent by always
picking the first one we found.

Benjamin Kramer b6aed5f441 [include-fixer] Autodetect yaml databases in parent directories.
This looks for find_all_symbols_db.yaml in all parent directories of the
source file (like we do for compile_commands.json) so we don't have to
pass the path manually.

Benjamin Kramer 683e592ff3 [find-all-symbols] Parallelize the merge step.
There is still more parallelism to get here because we synchonize on the
actual uniquing but just doing YAML parsing in parallel already gives a
significant speedup.

Merging all symbols in LLVM+clang+compiler-rt+lld+libc++, 48 cores.

Benjamin Kramer 027163e98b [find-all-symbols] Fix racy yaml file writing.
If multiple find-all-symbols processes access the temporary directory
simultaneously with two files with the same name they would collide and
create a broken yaml file. Fix this by using the safe createUniqueFile
API from LLVM instead.

Benjamin Kramer 6b23626192 [include-fixer] Add a prototype for a new include fixing tool.
Summary:
The goal of this tool is fairly simple, look up unknown identifiers in a
global database and add the corresponding #include line. It accomplishes
this by hooking into Sema as an ExternalSemaSource and responding to typo
correction callbacks. This means we can see the unknown identifier before
it's being munged by error recovery.

This doesn't work perfectly yet as some typo corrections don't emit
callbacks (delayed typos), but I think this is fixable. We also handle
only one include at a time as this is meant to be run directly from
the editing environment eventually. Adding multiple includes at the same
time is tricky because of error recovery.

This version only has a a dummy database, so all you can do is fixing
missing includes of <string>, but the indexer to build a database will
follow soon.
