[PATCH] D34435: Use -NOT prefix instead of adding `not` to FileCheck.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu created this revision.

If we want to make sure that a particular string is not in an output,
the regular way of doing it is to add `-NOT` prefix instead of checking
if FileCheck resulted in an error.
