hoist some funky logic into CodeGenInstruction
from two places in CodeGenDAGPatterns.cpp, and use it in DAGISelMatcherGen.cpp instead of using an incorrect predicate that happened to get lucky on our current targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99726 91177308-0d34-0410-b5e6-96231b3b80d8
