52d75d7aed Fast table-based implementation of reciprocal (RCPSS/RCPPS)
This implemntation is much more clear than old one.
RSQRTSS/RSQRTPS coming soon.

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 ! ;)

1cd38bb7dd Recommitted SSE code reorganization.
Fix in FXSAVE/FXRESTOR opcodes -> If the OSFXSR bitCR4 is not set, the FXRSTOR instruction does not restore the states of the XMM and MXCSR registers.

9b2914fd1d - Temporarily revert Stanislav's changes between 2002-12-18 and 2002-12-19.
Because source files were added/removed it would require an update
  of the windows and macos project files, so I want to wait until after 2.0.
    M Makefile.in         1.51 back to 1.50
    M cpu.h               1.121 back to 1.120
    M fetchdecode.cc      1.37 back to 1.36
    M fetchdecode64.cc    1.33 back to 1.32
    M sse.cc              1.17 back to 1.16
    A sse2.cc             1.27 back to 1.26  (added back)
    R sse_move.cc         removed
    R sse_pfp.cc          removed
- to bring these changes back again, all we have to do is
  "cvs update -j tmp-before1 -j tmp-after1"

aa361badf2 Reorganized SSE/SSE2 code
sse.cc -> general SSE stuff and SSE integer (MMX extensions)
sse_move.cc -> memory transfer and shuffle opcodes
sse_pfp.cc -> packed floating point operations
