Always use const param envs for const eval. 
Nothing else makes sense, and there is no "danger" in doing so, as it only does something if there are const bounds, which are unstable. This used to happen implicitly via the inferctxt before, which was much more fragile.

Use the constness from the param env instead of having a separate dimension for it

Rollup merge of #90833 - tmiasko:optimization-remarks, r=nikic 
Emit LLVM optimization remarks when enabled with `-Cremark`

The default diagnostic handler considers all remarks to be disabled by
default unless configured otherwise through LLVM internal flags:
`-pass-remarks`, `-pass-remarks-missed`, and `-pass-remarks-analysis`.
This behaviour makes `-Cremark` ineffective on its own.

Fix this by configuring a custom diagnostic handler that enables
optimization remarks based on the value of `-Cremark` option. With
`-Cremark=all` enabling all remarks.

Fixes #90924.

959dc77e6e Remove unnecessary use of include! in rustdoc test 
Using `include!` shouldn't affect the test. It was only added because:

> I replicated how it was performed in libstd. Since it's the main
> target of this fix, I thought it was the best way.

<https://github.com/rust-lang/rust/pull/52827/files#r207647331>

But it's unnecessary and adds unnecessary indirection.

Jack, this fix is much smaller in scope than what I think you were proposing in the issue. Let me know if you had a vision for a larger refactor here.

Perform Sync check on static items in wf-check instead of during const checks

r? `@RalfJung`

This check is solely happening on the signature of the static item and not on its body, therefor it belongs into wf-checking instead of const checking.

e6d2de9483 Auto merge of #91230 - eggyal:fallible-type-fold, r=jackh726 
Make `TypeFolder::fold_*` return `Result`

Implements rust-lang/compiler-team#432.

Initially this is just a rebase of `@LeSeulArtichaut's` work in #85469 (abandoned; see https://github.com/rust-lang/rust/pull/85485#issuecomment-908781112).  At that time, it caused a regression in performance that required some further exploration... with this rebased PR bors can hopefully report some perf analysis from which we can investigate further (if the regression is indeed still present).
