[M3devel] cg.alloca

[Jay K]

On NT386 the function is _chkstk, number of bytes in eax, return value in esp.
Notice how in parse.c I had to strcmp for the function name. A little gross, but it does work.
  And C/C++ work that way.
Notice how you implemented atomics.

I half agree though. It could be a function call even for NT386.
The atomics could be too.
