Rollup merge of #64394 - nnethercote:shrink-SubregionOrigin, r=Mark-Simulacrum
Shrink `SubregionOrigin`. It's currently 120 bytes on x86-64, due to one oversized variant (`Subtype`). This commit boxes `Subtype`'s contents, reducing the size of `SubregionOrigin` to 32 bytes. The change speeds things up by avoiding lots of `memcpy` calls, mostly relating to `RegionConstraintData::constraints`, which is a `BTreeMap` with `SubregionOrigin` values.
