[PATCH] D52895: [TailCallElim] Enable marking of calls with byval as tails

[Robert Lougher via Phabricator via llvm-commits]

rob.lougher added a comment.

I've updated the patch with the following changes:

1. Added a new inline test with local alloca.
2. Re-worded inline test comment.
3. Modified the first TailCallElim test to check that a byval parameter is neither an escape point or a use of the alloca.
