[X86][AVX] Extend hasVEX_WPrefix bit to accept WIG value (W Ignore) + update all AVX instructions with the new value.
Add WIG value to all of AVX instructions which ignore the W-bit in their encoding, instead of giving them the default value of 0.
This patch is needed for a follow up work on EVEX2VEX pass (replacing EVEX encoded instructions with their corresponding VEX version when possible).
