Rustdoc check option
The ultimate goal behind this option would be to have `rustdoc --check` being run when you use `cargo check` as a second step.

extend min_const_generics param ty tests
Apparently we never tested for `u128` and `i128` before this, so I added a test for all types which are allowed.

Implement destructuring assignment for structs and slices
This is the second step towards implementing destructuring assignment (RFC: rust-lang/rfcs#2909, tracking issue: #71126). This PR is the second part of #71156, which was split up to allow for easier review.
Note that the first PR (#78748) is not merged yet, so it is included as the first commit in this one. I thought this would allow the review to start earlier because I have some time this weekend to respond to reviews. If ``@petrochenkov`` prefers to wait until the first PR is merged, I totally understand, of course.
This PR implements destructuring assignment for (tuple) structs and slices. In order to do this, the following *parser change* was necessary: struct expressions are not required to have a base expression, i.e. `Struct { a: 1, .. }` becomes legal (in order to act like a struct pattern).
Unfortunately, this PR slightly regresses the diagnostics implemented in #77283. However, it is only a missing help message in `src/test/ui/issues/issue-77218.rs`. Other instances of this diagnostic are not affected. Since I don't exactly understand how this help message works and how to fix it yet, I was hoping it's OK to regress this temporarily and fix it in a follow-up PR.
Thanks to ``@varkor`` who helped with the implementation, particularly around the struct rest changes.

Reusing bindings causes errors later in lowering:
```
error[E0596]: cannot borrow `vec` as mutable, as it is not declared as mutable

incr-comp: hash and serialize span end line/column
Hash both the length and the end location (line/column) of a span. If we
hash only the length, for example, then two otherwise equal spans with
different end locations will have the same hash. This can cause a
problem during incremental compilation wherein a previous result for a
query that depends on the end location of a span will be incorrectly
reused when the end location of the span it depends on has changed. A
similar analysis applies if some query depends specifically on the
length of the span, but we only hash the end location. So hash both.

See #74890 for a more in-depth analysis.
I haven't thought about what other problems this root cause could be responsible for. Please let me know if anything springs to mind. I believe the issue has existed since the inception of incremental compilation.
Test default values for const parameters.
The last topic on #78433
I originally intended to place these tests in a single file, however, due to them being parser errors that are fatal, they must be in separate files to be detected.
Thanks, ``@lcnr`` for mentoring me on this PR.

Improve the page title switch handling between search and doc
The current behavior often "forgets" to update the page title when discarding/putting back the search results. This isn't optimal which is why I wrote this fix.
r? ``@jyn514``
extend const generics test suite
should implement most of #78433, especially all parts of [the hackmd](https://hackmd.io/WnFmN4MjRCqAjGmYfYcu2A?view) which I did not explicitly mention in that issue.

Add shortcut for theme picker menu
Follow-up of #78584
Just like you can focus the search input by pressing "S", you can now access the theme picker menu by pressing "T" and navigate through the options only using the keyboard.

Do not collect tokens for doc comments
Doc comment is a single token and AST has all the information to re-create it precisely.
Doc comments are also responsible for majority of calls to `collect_tokens` (with `num_calls == 1` and `num_calls == 0`, cc https://github.com/rust-lang/rust/pull/78736).
(I also moved token collection into `fn parse_attribute` to deduplicate code a bit.)

Support inlining diverging function calls
The existing heuristic does penalize diverging calls to some degree, but since
it never inlined them previously it might need some further modifications.
Additionally introduce storage markers for all temporaries created by
the inliner. The temporary introduced for destination rebrorrow, didn't
use them previously.
Add flags customizing behaviour of MIR inlining
* `-Zinline-mir-threshold` to change the default threshold.
* `-Zinline-mir-hint-threshold` to change the threshold used by
functions with inline hint.
Having those as configurable flags makes it possible to experiment with with
different inlining thresholds and substantially increase test coverage of MIR
inlining when used with increased thresholds (for example, necessary to test
#78844).
look at assoc ct, check the type of nodes
an example where types matter are function objects, see the added test which previously passed.
Now does a shallow comparison of unevaluated constants.

Support enable/disable sanitizers/profiler per target
This PR add options under `[target.*]` of `config.toml` which can enable or disable sanitizers/profiler runtime for corresponding target.
If these options are empty, the global options under `[build]` will take effect.
