New Revision: 97345

URL: http://llvm.org/viewvc/llvm-project?rev=97345&view=rev
Log:
remove a bogus pattern, which had the same pattern as STDU
but codegen'd differently.  This really wanted to use some
sort of subreg to get the low 4 bytes of the G8RC register
or something.  However, it's invalid and nothing is testing
it, so I'm just zapping the bogosity.
