target-arm: Avoid "1 << 31" undefined behaviour
Avoid the undefined behaviour of "1 << 31" by using 1U to make the shift be of an unsigned value rather than shifting into the sign bit of a signed integer. For consistency, we make all the CPSR_* constants unsigned, though the only one which triggers undefined behaviour is CPSR_N.
