Auto-Generated File Missing When Targeting LLVMCore, Causing Dredd Mutation Failure

[JonathanFoo0523]

The attempt to have all auto-generated code in place for Dredd, as noted in README -

cmake --build "${BUILD_DIR}" --target LLVMCore

doesn’t generate llvm/Frontend/OpenMP/OMP.h.inc, and dredd failed to mutate llvm/lib/Transforms/IPO/OpenMPOpt.cpp as a result.

Instead, running

cmake --build "${BUILD_DIR}" --target all

fix this issue, but this requires a long build time.

We should find a way to filter out the necessary targets while still ensure all auto-generated code is in place.

Thanks. In the worst case, I think it's OK to require building with --target all, as this is a one-off thing.
