[llvm-dev] RFC: [FileCheck] CHECK-DAG for multiple occurrences of string

I think #1 is much more intuitive and easy to describe/document than #2.
Changing the meaning of DAG in that way is highly unlikely to affect any 
existing test, IMO.  And if it does, my first expectation is that the test 
wasn't doing what the author intended anyway.
