--- Comment #7 from Richard Sandiford <rsandifo at gcc dot gnu.org> ---
I suppose the ZIP1 patterns should just have 64-bit inputs,
rather than going to the trouble of creating paradoxical subregs.

But machine_function is a GTYed structure, so the reference itself should
prevent GC. I don't think we should be in the practice of explicitly
ggc_free()ing RTL, since callers don't generally know what other references
there might be.
