src/sys/arch/i386/include: mcontext.h npx.h
Remove the fields from 'struct save87' and 'struct fxsave' that were used
to save the control word and tag word on fp faults.
Nothing I could find looked at them before I removed the code that wrote them.
It might appear that these fields got exported to userspace (via mcontext),
but that code carefully avoided those fields.
I've also deleted some very historic fields from the union inside __fpregset_t
this doesn't affect its size.
The __fpregset_t fields are now the same size as the ones in the pcb.
Which is good because they get cast to each other in a few places.
