[PATCH] D58784: [FileCheck]Remove assertions that prevent matching an empty string at file start before CHECK-NEXT/SAME

[Paul Robinson via Phabricator via llvm-commits]

probinson added a comment.

So we didn't have any tests that verified the assertion?  That was an oversight. 
FTR, the `CHECK: {{^$}}` is ensuring the first line is empty? I see that CHECK-EMPTY isn't allowed as the first directive, unfortunately.
