Teach TableGen to pre-calculate register enum values when creating the CodeGenRegister entries. Use this information to more intelligently build the literal register entires in the DAGISel matcher table. Specifically, use a single-byte OPC_EmitRegister entry for registers with a value of less than 256 and OPC_EmitRegister2 entry for registers with a larger value. rdar://9066491 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127456 91177308-0d34-0410-b5e6-96231b3b80d8
