Ryan Houdek 96aafb4f07 AVX128: Implement support for vmovddup
This instruction is a little weird.
When accessing memory, the 128-bit operating size of the instruction
only loads 64-bits.
Meanwhile the 256-bit operating size of the instruction fetches a full
256-bits.

Theoretically the hardware could get away with two 64-bit loads or a
wacky 24-byte load, but it looks like to simplify hardware they just
spec'd it that the 256-bit version will always load the full range.
