Auto merge of #75155 - davidtwco:polymorphization-incr-comp-optimisations, r=lcnr
polymorphization: various improvements
This PR includes a handful of polymorphisation-related changes:
- @Mark-Simulacrum's suggestions [from this comment](https://github.com/rust-lang/rust/pull/74633#issuecomment-668684433):
- Use a `FiniteBitSet<u32>` over a `FiniteBitSet<u64>` as most functions won't have 64 generic parameters.
- Don't encode polymorphisation results in metadata when every parameter is used (in this case, just invoking polymorphisation will probably be quicker).
- @lcnr's suggestion [from this comment](https://github.com/rust-lang/rust/pull/74717#discussion_r463690015).
- Add an debug assertion in `ensure_monomorphic_enough` to make sure that polymorphisation did what we expect.
