ec557aa818 Auto merge of #64949 - nnethercote:avoid-SmallVec-collect, r=zackmdavis 
Avoid `SmallVec::collect`

We can get sizeable speed-ups by avoiding `SmallVec::collect` when the number of elements is small.

Rollup merge of #65181 - nikomatsakis:lazy-norm-anon-const-push-1, r=varkor 
fix bug in folding for constants

These was a bug in the folding for constants that caused it to overlook bound regions. This branch includes some other little things that I did while trying to track the bug down.

0b58d9d124 correct bug in the "has escaping regions" visitor 
Existing code could overlook types/substitutions that are
embedded in (e.g.) an unevaluated constant.

Deny specializing items not in the parent impl

Part of https://github.com/rust-lang/rust/issues/29661 (https://github.com/rust-lang/rfcs/pull/2532). At least sort of?

This was discussed in https://github.com/rust-lang/rust/pull/61812#discussion_r300504114 and is needed for that PR to make progress (fixing an unsoundness).

One annoyance with doing this is that it sometimes requires users to copy-paste a provided trait method into an impl just to mark it `default` (ie. there is no syntax to forward this impl method to the provided trait method).

This is just moving them out to librustc_passes -- I've not measured compile time or run time. I don't expect any significant impact, but this seems prudent regardless.

5515a97646 Introduce a special case in IntRange::from_const. 
The `if let Some(val) = value.try_eval_bits(...)` branch in `from_const()` is
very hot for the `unicode_normalization` benchmark.

This commit introduces a special-case alternative for scalars that avoids
`try_eval_bits()` and all the functions it calls (`Const::eval()`,
`ConstValue::try_to_bits()`, `ConstValue::try_to_scalar()`, and
`Scalar::to_bits()`), instead extracting the result immediately.

The type and value checking done by `Scalar::to_bits()` is replicated by moving
it into a new function `Scalar::check_raw()` and using that new function in the
special case.

PR #64673 introduced some special-case handling of scalar types in
`Const::try_eval_bits()`. This handling is now moved out of that function into
the new `IntRange::integral_size_and_signed_bias` function.

This commit reduces the instruction count for
`unicode_normalization-check-clean` by about 10%.

Rollup merge of #65026 - petrochenkov:ice1, r=eddyb 
metadata: Some crate loading cleanup

So, my goal was to fix caching of loaded crates which is broken and causes ICEs like #56935 or #64450.
While investigating I found that the code is pretty messy and likes to confuse various things that look similar but are actually different.
This PR does some initial cleanup in that area, I hope to get to the caching itself a bit later.
