[PATCH] D65334: [llvm] [FileCheck] Use FILECHECK_DUMP_INPUT_ON_FAILURE only when non-empty

[Michał Górny via Phabricator via llvm-commits]

mgorny added a comment.

We are using it to force verbose output on buildbot ;-). But setting to an empty value should be very uncommon. The uses I've been able to grep in LLVM all set it to `1`.
