cond.md (movqicc_<code>_<mode>): Remove mode of conditional.

Browse Source 
* config/m32c/cond.md (movqicc_<code>_<mode>): Remove mode of
conditional.
(movhicc_<code>_<mode>): Likewise.
* config/m32c/m32c.c (encode_pattern_1): Specialise PSImode
subregs.
(m32c_eh_return_data_regno): Change to using memregs to avoid
tying up all the compute regs.
(m32c_legitimate_address_p) Subregs are not valid addresses.
