Fix stack frame layout.
...
f8-f15 are callee-saved (not f0,f2,f4 and f6). There isn't space
for them in the caller's stack frame so we need to increase the
size of the interpreter's stack frame.

Fixup the save/restore register macros.
...
I believe these macros obey the C calling convention, so we need to
allocate our stack frame and save all callee-save registers. We
can tune it later if it turns out we don't need all the registers.

Add preliminary frame offsets.
...
These are educated guesses at this point. We might need more stack space because
we don't have many free registers available.
