/* This code is equivalent to emitx64.c but pre-allocates stack
* space and uses mov instead of push/pop instructions to access
* the temporary stack. It runs in similar time, but uses 3*n
* more bytes, where n is number of push/pop instructions.
*
* This code is preferred because it keeps the stack aligned on a
* 16 byte boundary.
*
* Improvements:
* Doesn't call stub functions, does all the work inline.
* Has optimisations for loading i64s to stack.
