[PATCH] D40613: [LoopIdiom] Recognize unordered atomic memset

[Daniel Neilson via Phabricator via llvm-commits]

dneilson created this revision.

This expands the loop idiom recognition pass to recognize the unordered
atomic memset pattern. This pattern is the same pattern as a regular memset
except that the stores are unordered atomic, and limited to register size.
