Checkpoint some of what I was starting to tinker with for having some
different context support for 32 vs 64 bit processes.  This simply omits
the save/restore of the segment selector registers for non 32 bit
processes.  This avoids the rdmsr/rwmsr juggling when restoring %gs
clobbers the kernel msr that holds the gsbase.

However, I suspect it might be better to conditionally do this at
user<->kernel transition where we wouldn't need to do the juggling in the
first place.  Or have per-thread extended context save/restore hooks.
