Various tests had sprung up over the years which had --check-prefix=ABC on the RUN line, but "CHECK-ABC:" later on. This happened to work before, but was strictly incorrect. FileCheck is getting stricter soon though. Patch by Ron Ofir. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188173 91177308-0d34-0410-b5e6-96231b3b80d8
