[PATCH] D25742: Remove debug location from common tail when tail-merging

[Robert Lougher via llvm-commits]

I've had to revert this as it caused a ubsan test to unexpectedly fail (vptr.cpp).  As I don't know much about these tests I need to do some investigation into the failure.  I suspect the test was reliant on a debug location from a common-tail.
