[PATCH] D95424: [CodeGenPrepare] Also skip lifetime.end intrinsic when check return block in dupRetToEnableTailCallOpts

Hi,
This transformation is basically removing lifetime.end, is my understanding right?

In terms of correctness, this is fine IMO because removing lifetime.end makes the program more defined.
It is also syntactically fine to have an unmatched lifetime.start because LLVM already removes unreachable code that may contain lifetime.end.
