[clang] [llvm] OpenMP: Accept amdgpu name in arch directive (PR #201789)

[Matt Arsenault via cfe-commits]

https://github.com/arsenm created https://github.com/llvm/llvm-project/pull/201789

Accept amdgpu as an alias for amdgcn as part of the general
trend of preferring the amdgpu name. This is so the name is
consistent in the future when the triple arch name changes.
