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

Standartization of Bochs instruction handlers.
...
Bochs instruction emulation handlers won't refer to direct fields of instructions like MODRM.NNN or MODRM.RM anymore.
Use generic source/destination indications like SRC1, SRC2 and DST.
All handlers are modified to support new notation. In addition fetchDecode module was modified to assign sources to instructions properly.
Immediate benefits:
- Removal of several duplicated handlers (FMA3 duplicated with FMA4 is a trivial example)
- Simpler to understand fetch-decode code
Future benefits:
- Integration of disassembler into Bochs CPU module, ability to disasm bx_instruction_c instance (planned)
Huge patch. Almost all source files wre modified.

with --enable-avx option. When compiled in, AVX still has to be enabled
using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.

instructions support can be enabled using .bochsrc CPUID option.
