Tracked down the crash, which was argument-evaluation-order UB
in the wrapping indexStandardLibrary().
Sorry for the churn!
This reverts commit 77533ea443.
This reverts commit ccdb56ac10.
Still seeing windows failures on GN bots: http://45.33.8.238/win/58316/step_9.txt
Unfortunately I can't debug these at all - it's a bare unsymbolized
stacktrace, and I can't reproduce the failure.
This provides a nice "warm start" with all headers indexed, not just
those included so far.
The standard library is indexed after a preamble is parsed, using that
file's configuration. The result is pushed into the dynamic index.
If we later see a higher language version, we reindex it.
It's configurable as Index.StandardLibrary, off by default for now.

New values:
- Split Dynamic into Open/Preamble
- Add Background (previously was just Unknown)
- Soon: stdlib index
This requires extending to 16 bits, which fits within the padding of Symbol.
Unfortunately we're also *serializing* SymbolOrigin as a fixed 8 bits.
Stop serializing SymbolOrigin:
- conceptually, the source is whoever indexes or *deserializes* a symbol
- deserialization takes SymbolOrigin as a parameter and stamps it on each sym
- this is a breaking format change

Makes it easier to diagnose remote index issues with --debug-origins flag.

Summary:
o Lex the code to get the identifiers and put them into a "symbol" index.
o Adds a new completion mode without compilation/sema into code completion workflow.
o Make IncludeInserter work even when no compile command is present, by avoiding
inserting non-verbatim headers.
