Use wrapper functions consistently. Either reference the flag everywhere
or use the wrapper everywhere.

There are many places in the patch where both interrupt_handler and
fast_interrupt
are tested. These can be eliminated by setting the interrupt_handler flag when
you see fast_interrupt and checking for the correct registers to be saved in
microblaze_must_save_register().
+ if ((interrupt_handler && !prologue) ||( fast_interrupt && !prologue) )
+ if ((interrupt_handler && prologue) || (fast_interrupt && prologue))
Refactor. Fix spacing around parens.
