  Log Message:
  -----------
  [AMDGPU][Clang] add __builtin_amdgcn_av_(load|store)_b128 (#199176)

These builtins allow the program to request store-available and
load-visible accesses as described in #191246. Each of them takes a
__MEMORY_SCOPE_* operand that is then translated to target-specific
cache policy bits.

This patch was extracted from #172090.
