FYI, GCC generates this sequence as RTL rather than text, which means
it can be scheduled and optimized. Of course in optimized code we
don't expect the prologue skipper to work very well, and we use dwarf2
to bypass the prologue analyzer, so this may not be a big deal. But
I'm somewhat curious to see if we could make this extremely
sophisticated i386 prologue analyzer use Jim's prologue-value.[ch]
