...
Transmute big endian `s6_addr` and `[u16; 8]`
The old code already made the assumption to reinterpret
`Ipv6Addr` as `[u16; 8]`.
Glibc, Linux, FreeBSD, Win32 all makes this assumption.
The main motivation of using union it to better optimize code.
Godbolt: https://rust.godbolt.org/z/b4bGvo
Const is introducing unsafe when transmuting.

Improve `f32` and `f64` primitive documentation
I noticed that the docs for the primitive floats were fairly short. I first only wanted to add the IEEE specification information (compare [the reference](https://doc.rust-lang.org/reference/types/numeric.html )), but then also added some more beginner-friendly docs. Let me know what you think!

evaluate required_consts when pushing stack frame in Miri engine
[Just like codegen](https://github.com/rust-lang/rust/pull/70820/files#diff-32c57af5c8e23eb048f55d1e955e5cd5R194 ), Miri needs to make sure all `required_consts` evaluate successfully, to catch post-monomorphization errors.
While at it I also moved the const_eval error reporting logic into rustc_mir::const_eval::error; there is no reason it should be in `rustc_middle`. I kept this in a separate commit for easier reviewing.
Helps with https://github.com/rust-lang/miri/issues/1382 . I will add a test on the Miri side (done now: https://github.com/rust-lang/miri/pull/1504 ).

Rollup merge of #75337 - davidtwco:polymorphization-75255-fixes, r=eddyb
...
instance: only polymorphize upvar substs
This PR 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.
Due to an oversight on my part, when landing #75260 and #75255 , some tests started failing when polymorphization was enabled that I didn't notice until after landing - this PR fixes the regressions from #75255 . #75336 has been filed to make sure that we don't forget to try make this change again in future, as it does enable some optimisations.

Don't try to use wasm intrinsics on vectors
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`.

Avoid deleting temporary files on error

Clippy pointer cast lint experiment
This PR is an experiment about exposing more parts of `rustc_typeck` for use in `clippy`. In particular, the code that checks where a cast is valid or not was exposed, which necessitated exposing [`FnCtxt`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_typeck/check/struct.FnCtxt.html ), and figuring out how to create an instance of that type inside `clippy`.
This was prompted by [this clippy issue](https://github.com/rust-lang/rust-clippy/issues/2064 ).

Avoid or_fun_call for const_fn with no args
Based on #5682 by @lzutao
This avoids a subset of false positives, specifically those related to `const fn`s that take no arguments.
For the rest, a much more involved fix would be needed, see https://github.com/rust-lang/rust-clippy/pull/5682#issuecomment-638681210 .
So this does *not* solve #5658
changelog: Avoid triggering [`or_fun_call`] with `const fn`s that take no arguments.
