A decode through the integer operator set lowers its set and loads each graph,
the bounds pass included, on every call. int_set_cache::LoadedSets keeps a set
once it has loaded, keyed by (capability, lowering, profile, SHA-256 of the
listing of the members read), within a byte budget (256 MiB, LRU, 0 = off).
int_payload::decode_int / declared_cost and int_synth::decode_from_spec take
the load step from it; every other check runs as before. A refused set is
never kept. wai_ops::Graph::heap_bytes counts an entry's graphs.
Committed before the first build; results follow.
