Conrad Meyer dc6a82801d x86: Add dynamic interrupt rebalancing 
Add an option to dynamically rebalance interrupts across cores
(hw.intrbalance); off by default.

The goal is to minimize preemption. By placing interrupt sources on distinct
CPUs, ithreads get preferentially scheduled on distinct CPUs.  Overall
preemption is reduced and latency is reduced. In our workflow it reduced
"fighting" between two high-frequency interrupt sources.  Reduced latency
was proven by, e.g., SPEC2008.
