CPU_BUSY_CYCLE(): A new MI statement for busy loop power reduction
The new CPU_BUSY_CYCLE() may be put in a busy loop body so that CPU can reduce
power consumption, as Linux's cpu_relax() and FreeBSD's cpu_spinwait(). To
start minimally, use PAUSE on i386/amd64 and empty on others. The name is
chosen following the existing cpu_idle_*() functions. Naming and API may be
polished later.
