using a simple hypervisor call. Implement this.

SPARC T4 and later have a pause instruction to voluntarily pause a virtual
processor in order to give other strands a chance to run. Use it in
__mp_lock_spin_hook() to avoid wasting CPU cycles if we're waiting for
the kernel or scheduler locks. This is instruction is patched in, just like
we already do for the sleep instruction on SPARC64 VI processors. We look
at the hwcap-list property of the cpu nodes in the machine description to
decide whether the pause instruction is available.

Replace a plethora of historical protection options with just
PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h.
PROT_MASK is introduced as the one true way of extracting those bits.
Remove UVM_ADV_* wrapper, using the standard names.
