x86/insn: Add support for APX EVEX instructions to the opcode map

Browse Source 
To support APX functionality, the EVEX prefix is used to:

 - promote legacy instructions
 - promote VEX instructions
 - add new instructions

Promoted VEX instructions require no extra annotation because the opcodes
do not change and the permissive nature of the instruction decoder already
allows them to have an EVEX prefix.

Promoted legacy instructions and new instructions are placed in map 4 which
has not been used before.

Create a new table for map 4 and add APX instructions.

Annotate SCALABLE instructions with "(es)" - refer to patch "x86/insn: Add
support for APX EVEX to the instruction decoder logic". SCALABLE
instructions must be represented in both no-prefix (NP) and 66 prefix
forms.
