Summary:
Add fuzzy SymbolIndex, where identifier needn't match exactly.
The purpose for this is global autocomplete in clangd. The query will be a
partial identifier up to the cursor, and the results will be suggestions.
It's in include-fixer because:
- it handles SymbolInfos, actually SymbolIndex is exactly the right interface
- it's a good harness for lit testing the fuzzy YAML index
- (Laziness: we can't unit test clangd until reorganizing with a tool/ dir)
Other questionable choices:
- FuzzySymbolIndex, which just refines the contract of SymbolIndex. This is
an interface to allow extension to large monorepos (*cough*)
- an always-true safety check that Identifier == Name is removed from
SymbolIndexManager, as it's not true for fuzzy matching
- exposing -db=fuzzyYaml from include-fixer is not a very useful feature, and
a non-orthogonal ui (fuzziness vs data source). -db=fixed is similar though.

- Refactor the external sema source into a visible class
- Add support for emitting FixIts
- Wrap up include fixer as a plugin as I did with clang-tidy
Test case will follow as soon as I wire this up in libclang.

Summary:
The find-all-symbols tool generates a yaml symbol database for
include-fixer.
The symbol matcher is originally written by Xiaoyi Liu.

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.
