Subject: remove a bogus pattern, which had the same pattern as STDU
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9fa200d2a2360412465bbd6cfb485af2e9d5b1b4;p=oota-llvm.git

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.
