cd79fe5f31 Fix 386 register save/restore (FS & GS destroyed across EXEC - SF bug: 3090610) 
Involves:
* before calling INT24 restore 386 registers. Protect again when
  re-entering DOS for "(A)bort"
* INT21/AH=4C and variations restore 386 registers from the user stack
* INT23 (ctrl-break) restores 386 registers
* INT2F/AH=14 protects 386 registers.
* EXECRH is marked to potentially modify FS/GS for OW.

versions of NASM for more compact code, and adjust silent relocation segments.
