The current AMD64 compilers don't support _asm.  It's all intrinsic functions.
But it does come with a macro assembler.

I used /Ob2.  Sorry.

cl /D_CONSOLE /DWIN32 /O2 /Ot /Og /Ob2 /Oi /Oy:

Total nodes: 89913841
Raw nodes per second: 2140805
Total elapsed time: 42
SMP time-to-ply measurement: 15.238095


I can however, squeeze 163k out of the 32-bit version.
