Summary: As part of this * Emitted instructions now have named MachineInstr variables associated with them. This isn't particularly important yet but it's a small step towards multiple-insn emission. * constrainSelectedInstRegOperands() is no longer hardcoded. It's now added as the ConstrainOperandsToDefinitionAction() action. COPY_TO_REGCLASS uses an alternate constraint mechanism ConstrainOperandToRegClassAction() which supports arbitrary constraints such as that defined by COPY_TO_REGCLASS.
