. Updates to get X86, MXX and 3DNow assembler code working with Watcom

   C++ and NASM. This includes lots of _ASMAPI macros to ensure that
   assembler functions are prototyped as __cdecl, as Watcom C++ uses
   register calling conventions by default.
 . Misc fixes to files to remove warnings generated by Watcom C++.
