This is a FIXME that I need to free a constraint letter (probably the existing
R) as a constraint for (MEM reg), or more to the point, a side-effect-free
memory constraint: the libstdc++ asms are buggy and could get autoincrement.
Actually, there should be a generic constraint letter for that: just as "V" is
disjoint to "o", there needs to be a disjunction for "<>".
You may think so, but "o" is not always usable for this case.
