Emit redundant opcode checks for andimm and orimm tests at root so that we get grouping at the top level. Add an optimization to reorder type check & record nodes after opcode checks. We prefer to expose tree shape matching which improves grouping and will enhance the next optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97432 91177308-0d34-0410-b5e6-96231b3b80d8
