Rollup merge of #64532 - ecstatic-morse:dataflow-cursor-get, r=tmandry 
Replace `state_for_location` with `DataflowResultsCursor`

These are two different ways of getting the same data from the result of a dataflow analysis. However, `state_for_location` goes quadratic if you try to call it for every statement in the body.

Rollup merge of #64348 - arnohaase:pr_documentation_spin_loop_hint, r=alexcrichton 
PR: documentation spin loop hint

The documentation for 'spin loop hint' explains that yield is better if the lock holder is running on the same CPU. I suggest that 'CPU or core' would be clearer.

Rollup merge of #64528 - Aaron1011:fix/proc-macro-type, r=alexcrichton 
Load proc macro metadata in the correct order.

Serialized proc macro metadata is assumed to have a one-to-one
correspondence with the entries in static array generated by proc_macro_harness.
However, we were previously serializing proc macro metadata in a
different order than proc macros were laied out in the static array.
This lead to us associating the wrong data with a proc macro when
generating documentation, causing Rustdoc to generate incorrect docs for
proc macros.

This commit keeps track of the order in which we insert proc macros into
the generated static array. We use this same order when serializing proc
macro metadata, ensuring that we can later associate the metadata for a
proc macro with its entry in the static array.

Rollup merge of #64503 - RalfJung:miri-retag, r=oli-obk 
rename Allocation::retag -> with_tags_and_extra

This is more consistent with `Pointer::with_tag`. Also, "retag" is a [term from Stacked Borrows](https://github.com/rust-lang/unsafe-code-guidelines/blob/master/wip/stacked-borrows.md#retagging) with a [corresponding Machine hook](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_mir/interpret/machine/trait.Machine.html#method.retag), and this function has nothing to do with that other use of the term.

Rollup merge of #64502 - RalfJung:miri-toolstate, r=pietroalbini 
avoid duplicate issues for Miri build failures

Currently, when Miri regressed from test-pass to test-fail, we pen an issue -- and then when it regresses further from test-fail to build-fail, we open a *second* issue.

This changes the logic to avoid the redundant second issue for Miri.

Rollup merge of #64394 - nnethercote:shrink-SubregionOrigin, r=Mark-Simulacrum 
Shrink `SubregionOrigin`.

It's currently 120 bytes on x86-64, due to one oversized variant
(`Subtype`). This commit boxes `Subtype`'s contents, reducing the size
of `SubregionOrigin` to 32 bytes.

The change speeds things up by avoiding lots of `memcpy` calls, mostly
relating to `RegionConstraintData::constraints`, which is a `BTreeMap`
with `SubregionOrigin` values.

7efe1c6e67 Auto merge of #64525 - nikomatsakis:issue-64512-drop-order-tail-temp, r=davidtwco 
adjust desugaring for async fn to correct drop order

Old desugaring, given a user function body `{ $stmts; $expr }`

```
{
    let $param_pattern0 = $raw_param0;
    ...
    let $param_patternN = $raw_paramN;
    $stmts;
    $expr
}
```

New desugaring:

```
{
    let $param_pattern0 = $raw_param0;
    ...
    let $param_patternN = $raw_paramN;
    drop-temps {
        $stmts;
        $expr
    }
}
```

The drop-temps is an internal bit of HIR that drops temporaries from the resulting expression, but it should be equivalent to `return { $stmts; $expr }`.

9150f844e2 Auto merge of #64517 - alexcrichton:less-assertions, r=pietroalbini 
azure: Disable more LLVM/debug assertions in

This commit disables LLVM/debug assertions in our 5 slowest builders:

* i686-gnu
* i686-gnu-nopt
* i686-msvc-1
* i686-msvc-2
* x86_64-msvc-cargo

This is reducing the amount of test coverage for LLVM/debug assertions,
but we're just unfortunately running out of time on CI too many times.
Some test builds have shown that i686-gnu drops nearly an hour of CI
time by disabling these two assertions. Perhaps when we eventually get
4-core machines we can reenable these, but for now turn them off and
hook them up to the tracking issue at #59637 which will ideally be
repurposes to tracking all of these.
