Shilei Tian d4ecd1241c Revert "[OpenMP] Introduce kernel environment"
This reverts commit 35cfadfbe2decd9633560b3046fa6c17523b2fa9.

It makes a couple of buildbots unhappy because of the following test failures:
- `Transforms/OpenMP/add_attributes.ll'`
- `mapping/declare_mapper_target_data.cpp` on AMDGPU
