[PATCH] D20925: FileCheck: print input on errors

[Dmitry Vyukov via llvm-commits]

dvyukov created this revision.
dvyukov added a reviewer: llvm-commits.

FileCheck output is unactionable without intput. Print input on errors.

Are there any downsides of this?
I am ready to bargain about details like output only stdin.
