Support for MMX(TM) Technology

MMX(TM) technology is an extension to the Intel architecture (IA) instruction set. The MMX instruction set adds 57 opcodes and a 64-bit quadword data type, and eight 64-bit registers. Each of the eight registers can be directly addressed using the register names mm0 to mm7.

The prototypes for MMX technology intrinsics are in the mmintrin.h header file.
