Same some space by introducing shorthand byte codes for SSE prefixes
Properly done, all SSE instructions which has the 66/F2/F3 opcode
multiplex need two prefixes: one to control the use of OSP and one to
control the use of REP. However, it's a four-way select: np/66/F2/F3;
so introduce shorthand bytecodes for that purpose.
