arm: Fix the "c" constraint
The existing definition using register class CC_REG does not
work because CC_REGNUM does not support normal modes, and so
fails to match register_operand. Use a non-register constraint
and the cc_register predicate instead.
* config/arm/constraints.md (c): Use cc_register predicate.
