[PATCH] D22314: Make X86CallFrameOptimization work with code generated by fast isel.

[Michael Kuperstein via llvm-commits]

mkuper added a comment.

The change itself LGTM.

However, I don't think we should be running this pass at all with CodeGenOpt::None.
It was originally enabled only for -Os, and was later also enabled (by Hans, IIRC) for other opt level - but I think enabling it for -O0 was unintentional.
