[PATCH] D87858: [hip] Add HIP scope atomic ops.

[Michael Liao via Phabricator via cfe-commits]

hliao added a comment.

`singlethread` scope is added for completeness for the atomicity considering signal handling. It may not be applicable to GPU yet. We could simply ignore them in the late phases of the compiler. If desired, I may remove it as well.
