- 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

- Implement opStack protection: Use register %ebx for scaled indexed addressing mode to access opStack, make opStack push/pop operate on %bl portion only
...
- Add a third pass to VM compilation for computation of jump address offsets, removing the need to dereference into vm->instructionPointers[] for every call/jump
- Make use of 0F opcode prefix relative jumps
- Call Com_Memcpy for OP_BLOCK_COPY
- Fix several missing range checks for vm->dataBase memory access

needed there. Only the syscall function needs them.

VM_CallInterpreted hurts as VM_CallCompiled is only used on 32bit. Use

Patching from floam with some edits by myself:
...
I was working on a patch earlier to fix some more things up to be more
modern, and I added a couple lines from that cleanup patch I showed you
on irc. Some commented code was removed, some stuff was made to not be
broke (old head usage), the makefile should install things better, and a
a few GCC warnings were gagged. I also attempted to version it but
you'll probably want to change that to whatever versioning rules you
decide on using.
