x86: Add support for checking the raw state of an
 interrupt

In order to support hardware virtualization, we need to be able to
check if there are any interrupts pending irregardless of the
rflags.intf value. This changeset adds the checkInterruptsRaw() method
to the x86 interrupt control. It returns true if there are pending
interrupts that can be delivered as soon as the CPU is ready for
interrupt delivery.

This patch is a part of series of changes to add support for KVM on x86. See https://github.com/andysan/gem5/tree/kvm-x86 for the full series.
