Loosen up an assertion to allow intrinsics. I really have no idea what this code (findNonImmUse) does, so I'm only guessing that this is the right thing. It would be really really nice if this had comments and perhaps switched to SmallPtrSet (hint hint) :) This fixes rdar://5886601, a crash on gcc.target/i386/sse4_1-pblendw.c git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50252 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-25 05:13:01 +00:00			`; RUN: llvm-as < %s \| llc -mattr=+sse41`
