tried again later.
* interrupts.c (check_masked_interrupt): New function. (re)
checks for the posibility that a recent change to the MSR may have
made it possible to deliver an interrupt that was previously
masked be the EE bit.
* ppc-instructions (mtmsr, mfmsr, rfi): Check for posibility of
a pending interrupt being delivered using check_masked_interrupt().

leaving it to that module to handle both interrupt synchronization
and masking.
