Be more clever about regclasses in ScheduleDAGSDNodes::EmitCopyFromReg.
If two uses of a CopyFromReg want different regclasses, first try a common
sub-class, then fall back on the copy emitted in AddRegisterOperand. There is
no need for an assert here. The cross-class joiner usually cleans up nicely.
