Neel Natu 176666c2c9 Enable "Posted Interrupt Processing" if supported by the CPU. This lets us
inject interrupts into the guest without causing a VM-exit.

This feature can be disabled by setting the tunable "hw.vmm.vmx.use_apic_pir"
to "0".

The following sysctls provide information about this feature:
- hw.vmm.vmx.posted_interrupts (0 if disabled, 1 if enabled)
- hw.vmm.vmx.posted_interrupt_vector (vector number used for vcpu notification)

Tested on a Intel Xeon E5-2620v2 courtesy of Allan Jude at ScaleEngine.
