- Change the way DR_TRAP_FIXUP and V86_TRAP_FIXUP work so that they can be combined into TRAP_FIXUPS, which will also handle ABIOS Fixups later.
- Modified the way TRAP_FIXUPS and XXX_PROLOGS work, so that the fixup code doesn't depend on numerical values anymore, but instead on unique labels for each function (kitd thus becomes kitd_a and kitd_t, for entry and exit).
- Now we can put the TRAP_FIXUPS for the Interrupt Template as part of the code, and at the end.
- Enable Dr Save/Restore in lots of places where it was previously disable.
- Implement Dr Save/Restore in V86 traps.
