This commit restricts the substitution polymorphization added in #75255
to only apply to the tupled upvar substitution, rather than all
substitutions, fixing a bunch of regressions when polymorphization is
enabled.

Move to intra-doc links in library/std/src/path.rs
Helps with #75080.
@rustbot modify labels: T-doc, A-intra-doc-links, T-rustdoc
Known issue: The following links are broken (they are inside trait impls, undocumented in this file, inheriting from the original doc):
- [`Hasher`]
- [`Self`] (referencing `../primitive.slice.html`)
- [`Ordering`]
Previously if the compiler error'd, fatally, then temporary directories which
should be preserved by -Csave-temps would be deleted due to fatal compiler
errors being implemented as panics.
Updated tests and error msgs
Update stderr from test
Update w/ lcnr comments
Change some tests around, and also updated Ord implementation for ParamKindOrd
Update w/ nits from lcnr
Added this test to ensure that reordering the parameters only works with the feature const
generics enabled.
Fixed nits
Also added another test to verify that intermixed lifetimes are forbidden
Add back unwinding support for Sony PSP
This PR adds back unwinding support for the Sony PSP. The `mipsel-sony-psp` target works well with unwinding. In [rust-psp], we use the `panic_unwind` crate along with LLVM's libunwind to catch panics, run destructors, and print them to the debug screen without aborting all threads.

This commit fixes an issue with #74695 where the fptosi and fptoui
specializations on wasm were accidentally used on vector types by the
`simd_cast` intrinsic. This issue showed up as broken CI for the stdsimd
crate. Here this commit simply skips the specialization on vector kinds
flowing into `fpto{s,u}i`.

Add safety section to `NonNull::as_*` method docs
This basically adds the safety section of `*mut T::as_{ref,mut}` to the
same methods on `NonNull` with minor modifications to fit the
differences.
Part of #48929.
Simplify array::IntoIter
- Initialization can use `transmute_copy` to do the bitwise copy.
- `as_slice` can use `get_unchecked` and `MaybeUninit::slice_get_ref`,
and `as_mut_slice` can do similar.
- `next` and `next_back` can use the corresponding `Range` methods.
- `Clone` doesn't need any unsafety, and we can dynamically update the
new range to get partial drops if `T::clone` panics.

Implement `into_keys` and `into_values` for associative maps
This PR implements `into_keys` and `into_values` for HashMap and BTreeMap types. They are implemented as unstable, under `map_into_keys_values` feature.
Fixes#55214.

polymorphize: unevaluated constants
This PR makes polymorphization visit the promoted MIR of unevaluated constants with available promoted MIR instead of visiting the substitutions of that constant - which will mark all of the generic parameters as used; in addition polymorphization will now visit non-promoted unevaluated constants rather than visit their substs.
