Clippy Fix array-size-threshold config deserialization error
Complementary PR to https://github.com/rust-lang/rust/pull/108673 in order to also get this into the **next** beta.

Fix another ICE in `point_at_expr_source_of_inferred_type`
Types coming from method probes must only be investigated *structurally*, since they often contain escaping infer variables from generalization and autoderef. We already have a hack in this PR that erases variables from types, so just use that.
Fixes#108664
The note attached to this error is pretty bad:
```
here the type of `primes` is inferred to be `[_]`
```
But that's unrelated to the PR.
---
Side-note: This is a pretty easy to trigger beta regression, so I've nominated it. Alternatively, I'm slightly inclined to remove this code altogether until it can be reformulated to be more accurate and less ICEy.
Remove legacy PM leftovers
This drops two leftovers of legacy PM usage:
* We don't need to initialize passes anymore.
* The pass listing was still using legacy PM passes. Replace it with the corresponding new PM listing.
Deny capturing late-bound non-lifetime param in anon const
Introduce a new AnonConstBoundary so we can detect when we capture a late-bound non-lifetime param with `non_lifetime_binders` enabled.
In the future, we could technically do something like introduce an early-bound parameter on the anon const, and stick the late-bound param in its substs (kinda like how we turn late-bound lifetimes in opaques into early-bound ones). But for now, just deny it so we don't ICE.

This commit desugars the drop and replace deriving from an
assignment at MIR build, avoiding the construction of the
DropAndReplace terminator (which will be removed in a followign PR)
In order to retain the same error messages for replaces a new
DesugaringKind::Replace variant is introduced.
`mirror_expr_inner` calls `temporary_scope`. It then calls
`make_mirror_unadjusted` which makes an identical call to
`temporary_scope`.
This commit changes the `mirror_expr_inner` to get the `temp_lifetime`
out of the expression produced by `make_mirror_unadjusted`, similar to
how it currently gets the type.
Feed queries on impl side for RPITITs when using lower_impl_trait_in_trait_to_assoc_ty
I've added a test for traits that were already working and what I think is probably the last bit of infrastructure work needed.
In following PRs I'm going to start adding things TDD style, tests and code that make it work.

Make `ExprKind` the first field in `thir::Expr`
This makes its `Debug` impl print it first which is useful, as it's the most important part when looking at an expr.
Explain compile-time vs run-time difference in env!() error message
This PR is clarifying error message of `env!()` based on this user question: https://users.rust-lang.org/t/environment-variable-out-dir-is-undefined/90067
It makes it clear that `env!()` is for env variables defined at compile-time. There's special-case help text for common Cargo build script variables.
I've also rearranged the code to avoid allocating error message on the happy path when the env var is defined.
Point error span at Some constructor argument when trait resolution fails
This is a follow up to #108254 and #106477 which extends error span refinement to handle a case which I mistakenly believed was handled in #106477. The goal is to refine the error span depicted below:
```rs
trait Fancy {}
impl <T> Fancy for Option<T> where T: Iterator {}
fn want_fancy<F>(f: F) where F: Fancy {}
fn example() {
want_fancy(Some(5));
// (BEFORE) ^^^^^^^ `{integer}` is not an iterator
// (AFTER) ^ `{integer}` is not an iterator
}
```
I had used a (slightly more complex) example as an illustrative example in #108254 , but hadn't actually turned it into a test, because I had (incorrectly) believed at the time it was covered by existing behavior. It turns out that `Some` is slightly "special" in that it resolves differently from the other `enum` constructors I had tried, and therefore this test was actually broken.
I've now updated the tests to include this example, and fixed the code to correctly resolve the `Some` constructor so that the span of the error is reduced.
Support allocations with non-Box<[u8]> bytes
This is prep work for allowing miri to support passing pointers to C code, which will require `Allocation`s to be correctly aligned. Currently, it just makes `Allocation` generic and plumbs the necessary changes through the right places.
The follow-up to this will be adding a type in the miri interpreter which correctly aligns the bytes, using that for the Miri engine, then allowing Miri to pass pointers into these allocations to C calls.
Based off of #100467, credit to ```@emarteca``` for the code
