Rollup merge of #55956 - euclio:issue-55587, r=estebank 
add tests for some fixed ICEs

Fixes #55587.
Fixes #54348.

Looks like these ICEs are already fixed in nightly, so this PR just adds tests.

Rollup merge of #55781 - pnkfelix:issue-54382-more-precise-spans-for-temps-and-their-drops, r=davidtwco 
More precise spans for temps and their drops

This PR has two main enhancements:

 1. when possible during code generation for a statement (like `expr();`), pass along the span of a statement, and then attribute the drops of temporaries from that statement to the statement's end-point (which will be the semicolon if it is a statement that is terminating by a semicolon).
 2. when evaluating a block expression into a MIR temp, use the span of the block's tail expression (rather than the span of whole block including its statements and curly-braces) for the span of the temp.

Each of these individually increases the precision of our diagnostic output; together they combine to make a much clearer picture about the control flow through the spans.

Fix #54382

Rollup merge of #55837 - Centril:spökdata-skall-vara-strukturellt-matchbar, r=eddyb 
Make PhantomData #[structural_match]

fixes https://github.com/rust-lang/rust/issues/55028

This makes `PhantomData<T>` structurally matchable, irrespective of whether `T` is, per the discussion on this week's language team meeting (the general consensus was that this was a bug-fix).

All types containing `PhantomData<T>` and which used `#[derive(PartialEq, Eq)]` and were previously not `#[structural_match]` only because of `PhantomData<T>` will now be `#[structural_match]`.

Minor standard library constification

This PR makes some bits of the standard library into `const fn`s.
I've tried to be as aggressive as I possibly could in the constification.
The list is rather small due to how restrictive `const fn` is at the moment.

NLL Diagnostic Review 3: Unions not reinitialized after assignment into field

Fixes #55651, #55652.

This PR makes two changes:

First, it updates the dataflow builder to add an init for the place
containing a union if there is an assignment into the field of
that union.

Second, it stops a "use of uninitialized" error occuring when there is an
assignment into the field of an uninitialized union that was previously
initialized. Making this assignment would re-initialize the union, as
tested in `src/test/ui/borrowck/borrowck-union-move-assign.nll.stderr`.
The check for previous initialization ensures that we do not start
supporting partial initialization yet (cc #21232, #54499, #54986).

This PR also fixes #55652 which was marked as requiring investigation
as the changes in this PR add an error that was previously missing
(and mentioned in the review comments) and confirms that the error
that was present is correct and a result of earlier partial
initialization changes in NLL.

r? @pnkfelix (due to earlier work with partial initialization)
