LOG: [NFC][IR] Update StructuralHash comment

This patch updates a comment at the top of the structural hash
implementation that was made invalid by
64da0be1fc06ee2199bd27c980736986e0eccd9d. The class is now used for more
than just validating pass return status and is now the sole
implementation rather than being copied from somewhere.

Added: 
    

Modified: 
    llvm/lib/IR/StructuralHash.cpp

Removed:
