x86: Split apart x87's FSW and TOP, and add a missing break.

The FSW and TOP values are technically part of the same register, but
they have very different behaviors. One of them can be renamed and
float along without affecting global state, while the other requires
serialization. They just need to *look* like the same register when
read by the user.

Also, there was a missing break in setMiscRegNoEffect.
