x86: decode instructions with vex prefix
This patch updates the x86 decoder so that it can decode instructions with vex prefix. It also updates the isa with opcodes from vex opcode maps 1, 2 and 3. Note that none of the instructions have been implemented yet. The implementations would be provided in due course of time.
