Global scope is "" (was "")
Top-level namespace scope is "ns::" (was "ns")
Nested namespace scope is "ns::ns::" (was "ns::ns")
This composes more naturally:
- qname = scope + name
- full scope = resolved scope + unresolved scope (D42073 was the trigger)
It removes a wart from the old way: "foo::" has one more separator than "".
Another alternative that has these properties is "::ns", but that lacks
the property that both the scope and the name are substrings of the
qname as produced by clang.
This is re-landing r322996 which didn't build.

Summary:
This makes performance slower but more predictable (it always processes
every symbol). We need to find ways to make this fast, possibly by precomputing
short queries or capping the number of scored results. But our current approach
is too naive.
It also no longer returns results in a "good" order. In fact it's pathological:
the top N results are ranked from worst to best. Indexes aren't responsible for
ranking and MergedIndex can't do a good job, so I'm pleased that this will make
any hidden assumptions we have more noticeable :-)

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:
We now hide the static/dynamic split from the code completion, behind a
new implementation of the SymbolIndex interface. This will reduce the
complexity of the sema/index merging that needs to be done by
CodeComplete, at a fairly small cost in flexibility.

Summary:
To stay fast, it avoids deserializing anything outside the current file, by
disabling the LoadExternal code completion option added in r322377, when the

Summary:
Use the YAML-format symbols (generated by the global-symbol-builder tool) to
do the global code completion.
It is **experimental** only , but it allows us to experience global code
completion on a relatively small project.
Tested with LLVM project.

Summary:
We currently only collect external-linkage symbols in the collector,
which results in missing some typical symbols (like no-linkage type alias symbols).
This patch relaxes the constraint a bit to allow collecting more symbols.

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:
o Index interfaces to support using different index sources (e.g. AST index, global index) for code completion, cross-reference finding etc. This patch focuses on code completion.
The following changes in the original patch has been split out.
o Implement an AST-based index.
o Add an option to replace sema code completion for qualified-id with index-based completion.
o Implement an initial naive code completion index which matches symbols that have the query string as substring.

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.
