Rewritten handling of supported CPUID features to be able to handle large amount of CPU extensions
...
Now enable support for up to 128 CPU extensions and could easily extend it more
Also reduce memory footprint for bx_ia_opcodes.h arrays

Most of the instructions are implemented, more on the way.
+ few bugfixes for legacy AVX-512 emulation
AVX-512: Fixed bug in VCMPPS masked instruction implementation with 512-bit data size
AVX-512: Fixed AVX-512 masked convert instructions with non-k0 mask (behaved as non masked versions)
AVX-512: Fixed missed #UD due to invalid EVEX prefix fields for several AVX-512 opcodes (VFIXUPIMMSS/SD, FMA)

- Initial code for bx_Instruction_c disassembler which (together with Bochs decoder) will replace Bochs disasm module someday (very soon).
...
The code already knows to disasm most of the opcodes with their operands.
- Split according to OSIZE opcodes RDFSBASE/WRFSBASE / RDGSBASE/WRGSBASE both for disasm and performance
- Minimize amount of opcode forms in ia_opcodes.h again.
For example Udq means the same as Wdq but with no memory form.

Make possible to deliver instruction name for disasm directly from bx_ia_opcode_name (some opcodes were renamed).
...
Fixed bug in stack optimization in 64-bit mode (should result in some speedup)
ia_opcode.h - eliminate some OP_M cases when they actually meant "value of specific type in the memory"
example: "MOVBE Md, Gd" actually means "MOVBE Ed, Gd"which just not have reg/reg form.

Infrstructure change to support disasm of BxInstruction_c directly (without calling disasm)
...
The end goal will be also merging of disasm and cpu decoder to one module and remove the disasm.
Two bug fixes on the way:
TBM: fixed 64-bit TBM instructions with memory access (did 32-bit load instead of 64-bit)
BMI2: fixed operands order for PEXT/PDEP instructions
AVX2: fixed gather instruction decoding bug from decoder alias commit
