[PATCH] D121838: [WIP] Generalize "check-all" umbrella targets, use for check-clang-tools

[Sam McCall via Phabricator via cfe-commits]

sammccall added a comment.

This isn't ready for submission, there's some bits that touch the global variables in runtimes/, llvm/runtimes, and compiler-rt/test. Mostly to see the idea.

The main point is to allow check-clang-tools to cover the tests in clang-tools-extra without requiring them to be merged into a common test/ tree. (Thus enabling unmerging...)
It should also make it easy to add `check-all` targets to standalone builds of projects other than clang.

It probably makes sense to separate the behavior change for clang-tools-extra from the refactoring change to clang and llvm, combining them is mostly to make review clearer.
