[PATCH] D136939: [X86] Use default attributes for intrinsics

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

> This adds the default attributes (nocallback, nosync, nofree, willreturn) to some X86 intrinsics. This will be needed to avoid optimization regressions in the future.

Can you give us more details on what these optimizations are?
