x86: fix (dis)assembly of certain SSE2 insns in 16-bit mode
MOVNTI was wrongly assembled with a 66h prefix. Add IgnoreSize to
address this. It and the scalar to/from integer conversion insns also
were also wrongly using Ev / Gv, leading to 16-bit register names being
printed when 32-bit ones were meant.
Clone the 32-bit SSE2 test to cover both assembler and disassembler.
