Vegard Nossum 33f8c40a30 x86: add memory clobber in switch_to() ...

Segment registers are reloaded, so we should add a memory clobber. The
generated assembly code is identical in my tests, but this doesn't mean
it is necessarily true for all configurations/compilers.

x86_64 already has the memory clobber.
