John Baldwin 7fcca6096f Optimize the adaptive mutex spin a bit. Use a simple while loop with 
simple reads (and on IA32, a "pause" instruction for each interation of the
loop) to spin until either the mutex owner field changes, or the lock owner
stops executing.

Suggested by:	tanimura
Tested on:	i386
