d51aece0c1 Change BX_PANIC messages to BX_INFO when behaviour is accepted with Intel/AMD docs. 
Instructions MOV_CxRx and MOV_RxCx are not supported in v8086 mode according to Intel manuals.
Also these instructions are treated as register-to-register regardless to MODRM byte fields (according to AMD manuals)
Also commit fix for MOV_EwSw by Kevin

7f570b0150 Added PNI new streaming extensions instructions 
PNI could be enabled by setting BX_SUPPORT_PNI in config.h
After the feature will be fully validation I'll also add configure option.

The implemntation is ~complete. I've missed only three FPU new opcodes of FUSTTP instruction and MONITOR/WAIT instructions.

Enjoy ! ;)

6977467ed7 - fix flaw in IO bitmap permission handling (anonymous patch) 
From the author (see bug #663320) :
  In the code there is a check to verify that an IO bitmap
  is defined (io_base > BX_CPU_THIS_PTR
  tr.cache.u.tss386.limit_scaled) but there is no check if
  an accessed IO port's address actually falls within the
  defined limit of the TSS segment. So if I define an IO
  bitmap with 100 entries, port 101 may or may not be
  allowed depending on whatever bytes follow the TSS in
  memory
