[PATCH] D12875: Stripping invariant.group metadata in CodeGenPrepare

[Piotr Padlewski via llvm-commits]

Prazek added a comment.

Because that what CodeGenPrepare is for right? 
Because invariant.group.barrier is just intrinsic for optimizations purposes (like most of them if not all) we don't want to have calls to intrinsics functions in binaries,
so we remove all intrinsics in CodeGenPrepare.
