  Log Message:
  -----------
  [libomptarget] Implement most hip atomic functions in terms of intrinsics

Summary:
[libomptarget] Implement hip atomic functions in terms of intrinsics

All but atomicInc can be implemented using type generic clang intrinsics.
There is not yet a corresponding intrinsic for atomicInc in clang, only one in
LLVM. This patch leaves atomicInc as an unresolved symbol.
