It may be necessary to build additional targets before running
perf-training, the typical use case would be builtins and runtimes.
This change allows users to specify those dependencies as:
set(CLANG_PERF_TRAINING_DEPS builtins runtimes CACHE STRING "")

can tell) PGO_INSTRUMENT_LTO option in the Clang PGO caches.

After a lot of discussion in this diff the consensus was that it is really hard to guess the users intention with their LLVM build. Instead of trying to guess if Debug or Release is the correct default option we opted for just not specifying CMAKE_BUILD_TYPE a error.

Have the build work out of the box by forcing an LLD build.
That way, we don't require an external LTO-aware linker,
