Yep, there is quite some potential in this on x86. On x86-64 also stack
alignment prologues could be eliminated.
I guess the PIC tricks could do wonders for Mozilla. Additionally once this
works, we can move ahead with alternate entry points at gimple level possibly
re-implementing thunks/ctor clonning using them.
So if we finally get past the unwind info issues, I could start poking about
getting the PIC codegen working as a first experiment.
