[llvm-commits] PATCH: Add CHECK-FIRST/LAST to FIleCheck

[Argyris Kyrtzidis]

The attached patch adds 2 CHECK directives to the FileCheck utility:

CHECK-FIRST: check that the string appears in the first line (nothing  
comes before it)
CHECK-LAST: check that the string appears in the last line (nothing  
comes after it)

Please review.
