[PATCH] D39388: [RS4GC] Strip off invariant.start because memory locations arent invariant

[Anna Thomas via Phabricator via llvm-commits]

anna added a comment.

just a note: We haven't yet added support to forward loads/stores across calls when the calls are dominated by invariant.start. However, that's a perfectly legal transform, and this patch makes sure we don't miscompile when the transformation is supported.
