Scott Long 5ba0615c03 Optimize intr_execute_handlers() by combining the pic_disable_source() and 
pic_eoi_source() into one call.  This halves the number of spinlock operations
and indirect function calls in the normal case of handling a normal (ithread)
interrupt.  Optimize the atpic and ioapic drivers to use inlines where
appropriate in supporting the intr_execute_handlers() change.

This knocks 900ns, or roughly 1350 cycles, off of the time spent servicing an
interrupt in the common case on my 1.5GHz P4 uniprocessor system.  SMP systems
likely won't see as much of a gain due to the ioapic being more efficient than
the atpic.  I'll investigate porting this to amd64 soon.
