  1. Optimized (BMI2+PGO) builds for Linux+Windows. 

    See Makefile.bmi2 and use:
    make -f Makefile.bmi2 gull.syzygy.linux
    make -f Makefile.bmi2 gull.syzygy.windows

For Windows cross compilation is not supported.  Instead use MSYS2 configured
for 64-bit compilation.

Linux results (self-play versus old non-syzygy non-BMI2 Gull.linux):

LTC (60"+0.6", 1-thread, 6-man syzygy):

    Score: +1728-1351=6921

STC (10"+0.1", 1-thread, 6-man syzygy):

  1. Fix Gull pawn hash bug & other improvements 

    - Fix a bug (inherited from Gull 3) where PawnEntry->passer is never cleared.
- Shrink GPawnEntry to 16 bytes (down from 24).

  1. Small SMP optimiziations. 

    - I/O no longer requires locking - it is likely unnecessary
- Windows threads wait on a single event rather than an event-per-thread.
- Do not clear pawnhash (for fair comparison with Gull3).
