[PATCH] D104801: [MemCpyOpt] Enable memcpy optimizations unconditionally.

[Hendrik Greving via Phabricator via llvm-commits]

hgreving added a comment.

Besides that this patch created the intrinsics llvm.memset which in our target was unsupported, it also created pointers that may be invalid on the target, e.g. i8 addrspace(X)* where addrspace(X) only supports vector memory. While this is probably all solvable, please consider adding TTI switches for targets to disable this optimization (e.g. for the intrinsics).
