[InstSimplify] analyze (optionally casted) icmps to eliminate obviously false logic (PR27869)
...
By moving this transform to InstSimplify from InstCombine, we sidestep the problem/question
raised by PR27869:
https://llvm.org/bugs/show_bug.cgi?id=27869
...where InstCombine turns an icmp+zext into a shift causing us to miss the fold.

Make use of the END. facility on all files > 1K so that we aren't wasting CPU
cycles searching for RUN: lines that we'll never find.
