Improve wording of parse doc
Change:
```
`parse` can parse any type that...
```
to:
```
`parse` can parse into any type that...
```
Word `into` added to be more precise and in coherence with other parts of the doc.
Properly handle primitive disambiguators in rustdoc
Fixes#80559
r? ``@jyn514``
Is there a way to test that the generated intra-doc link is what I expect?
MIR Inline is incompatible with coverage
Fixes: #80060
Fixed by disabling inlining if `-Zinstrument-coverage` is set.
The PR also adds additional use cases to the coverage test for doctests.

Make `ExpnData` fields `krate` and `orig_id` private
These fields are only used by hygiene serialized, and should not be
accessed by anything outside of `rustc_span`.

```
`parse` can parse any type that...

to:
```
`parse` can parse into any type that...
```

Optimize DST field access
For
struct X<T: ?Sized>(T)
struct Y<T: ?Sized>(u8, T)
the offset of the unsized field is
0
mem::align_of_val(&self.1)
respectively. This patch changes the expression used to compute these
offsets so that the optimizer can perform this optimization.
Consider
```rust
fn f(x: &X<dyn Any>) -> &dyn Any {
&x.0
}
```
Before:
```asm
test:
movq %rsi, %rdx
movq 16(%rsi), %rax
leaq -1(%rax), %rcx
negq %rax
andq %rcx, %rax
addq %rdi, %rax
retq
```
After:
```asm
test:
movq %rsi, %rdx
movq %rdi, %rax
retq
```
Optimize away a `fs::metadata` call.
This also eliminates a use of a `Path` convenience function, in support
of #80741, refactoring `std::path` to focus on pure data structures and
algorithms.
* Rename `ModuleData.normal_ancestor_id` to `nearest_parent_mod`
`normal_ancestor_id` is a very confusing name if you don't already
understand what it means. Adding docs helps, but using a clearer and
more obvious name is also important.
* Rename `Resolver::nearest_mod_parent` to `nearest_parent_mod`
* Add more docs

Remove useless doc_alias feature gate
As `@jyn514` rightfully noted in https://github.com/rust-lang/rust/pull/80686 , this feature is no more. Therefore, cleanup time!

Add more code spans to docs in intrinsics.rs
I have added some more code spans in core/src/intrinsics.rs, changing some `=` to `==`, etc. I also changed the wording in some sections.

make sure that promoteds which fail to evaluate in dead const code behave correctly
https://github.com/rust-lang/rust/pull/80243 showed that we'll have to live with these kinds of failing promoteds for a while, so let's make sure we have a test that covers them.
./x.py clippy: allow the most noisy lints
This silences the following clippy lints in ./x.py clippy:
many_single_char_names (there are a lot of warnings caused by stdarch)
collapsible_if (can reduce readability)
type_complexity
missing_safety_doc (there are almost 3K warnings issued)
too_many_arguments
needless_lifetimes (people want 'tcx lifetimes etc)
wrong_self_convention (warns about from_..(), to_..(), into_..().. fns that do or do not take self by reference.
Just for clarification; this only changes the output of `x.py clippy` inside the rustc repo and does not change anything about clippy or how `cargo clippy` is run on peoples crates.
