- Add MASM assembler files for MSVC x64 projects to support vm_x86 in x64 mode - Clean up ftol()/snapvector() mess - Make use of SSE instructions for ftol()/snapvector() if available - move ftol/snapvector pure assembler to inline assembler, this will add x86_64 and improve support for different calling conventions - Set FPU control word at program startup to get consistent behaviour on all platforms
