Make x86's BT instruction matching more thorough, and add some
dagcombines that help it match in several more cases. Add several more cases to test/CodeGen/X86/bt.ll. This doesn't yet include matching for BT with an immediate operand, it just covers more register+register cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63266 91177308-0d34-0410-b5e6-96231b3b80d8
