Implement AVX512BW and AVX512DQ extensions published in recently published Intel Archtecture Extensions manual rev20.
...
https://software.intel.com/sites/default/files/managed/c6/a9/319433-020.pdf
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)

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.
