Not all downstream users may want to build all tools shipped with clang. `clang-repl` for us in particular can sometimes lead to flaky builds when testing a toolchain built with LTO.

This is a WIP patch that demonstrates:

- Allowing `clang-repl` to be built (by default) as part of `check-all`. Note that this doesn't remove it as a build target. It just makes it so that it's not built by default.
- Only running tests that require `clang-repl` via a `REQUIRES` line.
