* config/m32c/m32c.c (m32c_const_ok_for_constraint_p): Add ImB
constraint for single-bit-clear in lower byte of HI constant, vs
Imb which just ignores the upper byte.
* config/m32c/predicates.md (m32c_1mask8_operand): Use it.
* config/m32c/bitops.md (andhi3_16, andhi3_24): Use it.
(iorhi3_16): Check for single bit set, not single bit clear.
