[llvm] [Offload][CI] Enable offload runtime (PR #174955)

[Jan Patrick Lehr via llvm-commits]

https://github.com/jplehr created https://github.com/llvm/llvm-project/pull/174955

Offload and OpenMP have been disabled in pre-commit build and test for quite some time. Recently, some CMake changes were made and the build command in premerge testing seems to have changed.

This is to take another swing at enabling openmp and offload, at least, for building in premerge test.

Subject: [PATCH] [Offload][CI] Enable offload runtime

Offload and OpenMP have been disabled in pre-commit build and test for
quite some time. Recently, some CMake changes were made and the build
command in premerge testing seems to have changed.

This is to take another swing at enabling openmp and offload, at least,
for building in premerge test.
