Much like there are specialized variants of `mk_ty`. This will enable
some optimization in the next commit.
Also rename the existing `re_error*` functions as `mk_re_error*`, for
consistency.
interpret: rename Pointer::from_addr → from_addr_invalid
This function corresponds to `ptr::invalid` in the standard library; the previous name was not clear enough IMO.
Use derive attributes for uninteresting traversals
It appears that visiting and folding was implemented on `BitMatrix` solely so that the derive macros could be used on `GeneratorLayout`, however such implementation would not necessarily be correct for other uses (if there were any). Adding attributes to the derive macro is more correct and potentially more generally useful.

Refactor refcounted structural_impls via functors
The mapping of values in refcounted types can be extracted as a functor, simplifying the implementations in the type library (whose structural folding impls now all use such functors). This functor could also prove more generally useful elsewhere.
add an unstable `#[rustc_coinductive]` attribute
useful to test coinduction, especially in the new solver.
as this attribute should remain permanently unstable I don't think this needs any official approval. cc ``@rust-lang/types``
had to weaken the check for stable query results in the solver to prevent an ICE if there's a coinductive cycle with constraints.

Store metrics from `metrics.json` to CI PGO timer
With this change, we'll be able to easily see how long does it take to compile LLVM vs `rustc`.

Update the minimum external LLVM to 14
With this change, we'll have stable support for LLVM 14 through 16 (pending release).
For reference, the previous increase to LLVM 13 was #100460.

Remove needless supertrait constraints from Interner projections
These associated types are already all constrained to implement `Ord`, so specifically requiring its supertraits `Eq`, `PartialEq` and `PartialOrd` is superfluous.
