Peter Maydell 78dbbbe4df 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.
