OMG. Don't bother reducing. I can see the problem.
EVRP is fine, but when wrestrict runs, its quite late, and the CFG has

BTW, we're looking as to why there are so many calls to varying_p. Something
seems off.

rather than sticking to wide_ints. That's always (constant-time) more
expensive.

I see the following in perf top:
9.84% cc1plus[.] wide_int_to_tree_1
6.59% cc1plus[.] irange::varying_p
6.13% cc1plus[.] bitmap_bit_p
4.35% cc1plus[.]
