S12Z: GAS: Issue warning if TFR/EXG have identical source and destination.
It is permissible for the source and destination operands of TFR and EXG to be
the same register. However it is a pointless instruction and anyone writing it
has probably made a mistake. This change emits a warning if such an instruction
is encountered.

* config/tc-s12z.c (tfr): Emit warning if operands are the same.
