Don't serialize ExpnData for foreign crates
When we encode an ExpnId into the crate metadata, we write out the
CrateNum of the crate that 'owns' the corresponding `ExpnData`, which
is later used to decode the `ExpnData` from its owning crate.
However, we current serialize the `ExpnData` for all `ExpnIds` that we
serialize, even if the `ExpnData` was already serialized into a foreign
crate. This commit skips encoding this kind of `ExpnData`, which should
hopefully speed up metadata encoding and reduce the total metadata size.
FreeBSD 10 reached its end-of-life in October 2018, and that toolchain
caused issues in the LLVM 11 upgrade (#73526) that are resolved with the
toolchain from FreeBSD 11.
Unfortunately, sanitizers do not support versioned symbols[1],
so they break filesystem access via the legacy, pre-ino64 ABI.
To use sanitizers on FreeBSD >= 12, we need to build the libc
crate with LIBC_CI=1 to use the new ABI -- including the libc
used for std. But that removes the st_lspare field std was
expecting for the deprecated metadata extension.
Add a way to skip that field to allow the build to work.

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`.
