Not seeing any problems in this series. I was hoping it would remove more
lines of code than it adds, and it's the reverse, but that seems to be
mostly the new push/pop stuff. I'm taking it we couldn't just replace the
'mov' instructions in the save/restore macros..

I *do* ask that when we have code like this:

addq $8, %rsp

that "addq $8" would have a comment about what stack entry we're skipping.

I *think* it's 'orig_eax', but wouldn't it be nice to say so?
