x86: implements the simd128 ADDSUBPD instruction

This patch implements the simd128 ADDSUBPD instruction for the x86 architecture.

Tested with a simple program in assembly language which executes the
instruction.  Checked that different versions of the instruction are executed
by using the execution tracing option.
