6a83352aa3 Introduce RawVec::reserve_for_push. 
If `Vec::push`'s capacity check fails it calls `RawVec::reserve`, which
then also does a capacity check.

This commit introduces `reserve_for_push` which skips the redundant
capacity check, for some slight compile time speed-ups.

I tried lots of minor variations on this, e.g. different inlining
attributes. This was the best one I could find.

85ba6c7b34 Only show notable traits if both types are the same 
Checking only their DefId doesn't work because all slices have the same
fake DefId.

6db0a0e9a4 Auto merge of #91299 - cjgillot:expect-ldid, r=petrochenkov 
Take a LocalDefId in expect_*item.

Items and item-likes are always HIR owners.
When trying to find such nodes, there is no ambiguity, the `LocalDefId` and the `HirId::owner` always match.
In such cases, `local_def_id_to_hir_id` does not carry any meaningful information, so we can just skip calling it altogether.

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.

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.

Fix incorrect usage of EvaluatedToOk when evaluating TypeOutlives 
A global predicate is not guarnatenteed to outlive all regions.
If the predicate involves late-bound regions, then it may fail
to outlive other regions (e.g. `for<'b> &'b bool: 'static` does not
hold)

We now only produce `EvaluatedToOk` when a global predicate has no
late-bound regions - in that case, the ony region that can be present
in the type is 'static
