[PATCH] D59534: Enable tail call in MemCpyOptimization

[Hideto Ueno via Phabricator via llvm-commits]

I think so too.

As you said, I'd like to split TailCallElimPass into two passes, "TailCallMarkingPass" and "TailCallElimPass".

TailCallMarkingPass is only for marking function calls as "tail". 
New TailCallElimPass does what old TailCallElimPass did except for marking the calls.

I will make a new patch for these.
