tcg/i386: Add vector operations
The x86 vector instruction set is extremely irregular. With newer editions, Intel has filled in some of the blanks. However, we don't get many 64-bit operations until SSE4.2, introduced in 2009. The subsequent edition was for AVX1, introduced in 2011, which added three-operand addressing, and adjusts how all instructions should be encoded. Given the relatively narrow 2 year window between possible to support and desirable to support, and to vastly simplify code maintainence, I am only planning to support AVX1 and later cpus.
