  -----------
  [Docs][AMDGPU] fully specify volatile accesses in the memory model

A volatile access on AMDGPU includes store-available or load-visible semantics
at the widest scope supported by its address space:

- system scope for global/generic,
- workgroup scope for local (LDS)

This fully specifies the behavior that the LLVM memory model leaves
target-dependent, matching the implementation in SIMemoryLegalizer.
