fd383435f0 - 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.

fa06b26c88 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.

ff79cbd596 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
