Don't use the global check_interrupts variable. Add a per-cpu

checkInterrupts variable and use that to determine whether an interrupt
can occur on a given cycle.

arch/alpha/ev5.cc:
    XC -> CPU (and xc -> CPU) since we're really talking about a CPU here
    Don't use the global check_interrupts variable.  Add a per-cpu
    checkInterrupts variable and use that to determine whether an interrupt
    can occur on a given cycle.
