Sam McCall 2f760c44e6 [clangd] Rewrite of logic to rebuild the background index serving structures.
Summary:
Previously it was rebuilding every 5s by default, which was much too frequent
in the long run - the goal was to provide an early build. There were also some
bugs. There were also some bugs, and a dedicated thread was used in production
but not tested.

 - rebuilds are triggered by #TUs built, rather than time. This should scale
   more sensibly to fast vs slow machines.
 - there are two separate indexed-TU thresholds to trigger index build: 5 TUs
   for the first build, 100 for subsequent rebuilds.
 - rebuild is always done on the regular indexing threads, and is affected by
   blockUntilIdle. This means unit/lit tests run the production configuration.
 - fixed a bug where we'd rebuild after attempting to load shards, even if there
   were no shards.
 - the BackgroundIndexTests don't really test the subtleties of the rebuild
   policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough
   to pass the tests). Instead, we expose the rebuilder as a separate class and
   have fine-grained tests for it.

//===----------------------------------------------------------------------===//

Welcome to the repository of extra Clang Tools.  This repository holds tools
that are developed as part of the LLVM compiler infrastructure project and the
Clang frontend.  These tools are kept in a separate "extra" repository to
allow lighter weight checkouts of the core Clang codebase.

This repository is only intended to be checked out inside of a full LLVM+Clang
tree, and in the 'tools/extra' subdirectory of the Clang checkout.

All discussion regarding Clang, Clang-based tools, and code in this repository
should be held using the standard Clang mailing lists:
  http://lists.llvm.org/mailman/listinfo/cfe-dev

Code review for this tree should take place on the standard Clang patch and
commit lists:
  http://lists.llvm.org/mailman/listinfo/cfe-commits

If you find a bug in these tools, please file it in the LLVM bug tracker:
  http://llvm.org/bugs/
