Sam McCall abe3737350 [clangd] Sema ranking tweaks: downrank keywords and injected names.
Summary:
Injected names being ranked too high was just a bug.
The high boost for keywords was intended, but was too much given how useless
keywords are. We should probably boost them on a case-by-case basis eventually.

Eric Liu 09c3c37b72 [clangd] Boost completion score according to file proximity.
Summary:
Also move unittest: URI scheme to TestFS so that it can be shared by
different tests.

Sam McCall c3b5bad723 [clangd] Boost keyword completions.
Summary: These have few signals other than being keywords, so the boost is high.

Sam McCall 4caa85129f [clangd] Code completion: drop explicit injected names/operators, ignore Sema priority
Summary:
Now we have most of Sema's code completion signals incorporated in Quality,
which will allow us to give consistent ranking to sema/index results.

Therefore we can/should stop using Sema priority as an explicit signal.
This fixes some issues like namespaces always having a terrible score.

The most important missing signals are:
 - Really dumb/rarely useful completions like:
    SomeStruct().^SomeStruct
    SomeStruct().^operator=
    SomeStruct().~SomeStruct()
   We already filter out destructors, this patch adds injected names and
   operators to that list.
 - type matching the expression context.
   Ilya has a plan to add this in a way that's compatible with indexes
   (design doc should be shared real soon now!)

Sam McCall d9b54f0025 [clangd] Boost code completion results that are narrowly scoped (local, members)
Summary:
This signal is considered a relevance rather than a quality signal because it's
dependent on the query (the fact that it's completion, and implicitly the query
context).

This is part of the effort to reduce reliance on Sema priority, so we can have
consistent ranking between Index and Sema results.

Sam McCall c5707b6c36 [clangd] Extract scoring/ranking logic, and shave yaks.
Summary:
Code completion scoring was embedded in CodeComplete.cpp, which is bad:
 - awkward to test. The mechanisms (extracting info from index/sema) can be
   unit-tested well, the policy (scoring) should be quantitatively measured.
   Neither was easily possible, and debugging was hard.
   The intermediate signal struct makes this easier.
 - hard to reuse. This is a bug in workspaceSymbols: it just presents the
   results in the index order, which is not sorted in practice, it needs to rank
   them!
   Also, index implementations care about scoring (both query-dependent and
   independent) in order to truncate result lists appropriately.

The main yak shaved here is the build() function that had 3 variants across
unit tests is unified in TestTU.h (rather than adding a 4th variant).
