As far as I can tell, the only "use" of use_initial_val is defining
the pseudo-instruction in the md file, which causes the code in patch
1/3 to use it. I see no other references to it. As I understand, the
breakage from not having it (in the original 4.5-era patch) would be
when introducing references to __fpscr_values later, and no longer
having the GOT pointer, but that code is gone now.
