[Openmp-dev] AMDGPU and clang-tools-extra

spack install llvm at main does work on my workstation with ubuntu 20.04. rocm
is installed and amd pieces for OpenMP offload are rebuilt properly. I have
limited ideas about the experience on other OSes.

yeluo at epyc-server:~/opt/llvm-clang/llvm-project$ ls
libomp.so                      libomptarget-amdgcn-gfx803.bc
libomptarget-amdgcn-gfx700.bc  libomptarget-amdgcn-gfx900.bc
libomptarget-amdgcn-gfx701.bc  libomptarget-amdgcn-gfx906.bc
libomptarget-amdgcn-gfx801.bc  libomptarget.rtl.amdgpu.so

yeluo at epyc-server:~/opt/llvm-clang/llvm-project$ which clang-tidy

spack uses ENABLE_PROJECTS and doesn't use ENABLE_RUNTIMES right now.
So the output from building clang-tools-extra and openmp can be blended.
