-cpu/e132xs: Implemented pointer error exceptions for recompiler.

Browse Source 
* Implemented pointer error exceptions on attempting to use a zero
  address register (other than SR) in the recompiler.
* Also optimised load/store instructions a bit and reduced copy/paste.
* Fixed a couple of disassembler issues.

-misc/dgpix.cpp: Demoted The X-Files to not working with unemulated
 protection.
