Summary:
It's almost always identical to Name, and in fact we never used it (we used name
instead).
The only case where they differ is objc method selectors (foo: vs foo:bar:).
We can live with the latter for both name and filterText, so I've made that
change too.

Summary:
This is a convenient function when we try to get std::string of
SymbolID.

Summary:
LSP is using Line & column as symbol position, clangd needs to transfer file
offset to Line & column when sending results back to LSP client, which is a high
cost, especially for finding workspace symbol -- we have to read the file
content from disk (if it isn't loaded in memory).
Saving these information in the index will make the clangd life eaiser.

Summary:
o Collect suitable #include paths for index symbols. This also does smart mapping
for STL symbols and IWYU pragma (code borrowed from include-fixer).
o For global code completion, add a command for inserting new #include in each code
completion item.

Within a TU:
- as now, collect a declaration from the first occurrence of a symbol
(taking clang's canonical declaration)
- when we first see a definition occurrence, copy the symbol and add it
Across TUs/sources:
- mergeSymbol in Merge.h is responsible for combining matching Symbols.
This covers dynamic/static merges and cross-TU merges in the static index.
- it prefers declarations from Symbols that have a definition.
- GlobalSymbolBuilderMain is modified to use mergeSymbol as a reduce step.
Random cleanups (can be pulled out):
- SymbolFromYAML -> SymbolsFromYAML, new singular SymbolFromYAML added
- avoid uninit'd SymbolLocations. Add an idiomatic way to check "absent".
- CanonicalDeclaration (as well as Definition) are mapped as optional in YAML.
- added operator<< for Symbol & SymbolLocation, for debugging

Summary:
This would have caught a bug I wrote in an early version of D42049, where
an index user could overwrite data internal to the index because the Symbol is
not deep-const.
The YAML traits are now a bit more verbose, but separate concerns a bit more
nicely: ArenaPtr can be reused for other similarly-allocated objects, including
scalars etc.

Summary:
This improves a few things:
- the insert -> freeze -> read sequence is now enforced/communicated by the
type system
- SymbolSlab::const_iterator iterates over symbols, not over id-symbol pairs
- we avoid permanently storing a second copy of the IDs, and the
string map's hashtable
The slab size is now down to 21.8MB for the LLVM project.
Of this only 2.7MB is strings, the rest is #symbols * `sizeof(Symbol)`.
`sizeof(Symbol)` is currently 96, which seems too big - I think
SymbolInfo isn't efficiently packed. That's a topic for another patch!
Also added simple API to see the memory usage/#symbols of a slab, since
it seems likely we will continue to care about this.

Summary:
Symbols are not self-contained - it's only safe to hand them out if you
guarantee the lifetime of the underlying data.
Before this lands, I'm going to measure the before/after memory usage of the
LLVM index loaded into memory in a single slab.

Summary:
* The "Symbol" class represents a C++ symbol in the codebase, containing all the
information of a C++ symbol needed by clangd. clangd will use it in clangd's
AST/dynamic index and global/static index (code completion and code
navigation).
* The SymbolCollector (another IndexAction) will be used to recollect the
symbols when the source file is changed (for ASTIndex), or to generate
all C++ symbols for the whole project.
In the long term (when index-while-building is ready), clangd should share a
same "Symbol" structure and IndexAction with index-while-building, but
for now we want to have some stuff working in clangd.
