Add primitive module to libcore
This re-exports the primitive types from libcore at `core::primitive` to allow
macro authors to have a reliable location to use them from.

no more codegen for miri_start_panic
With https://github.com/rust-lang/miri/pull/1136 landed, we don't generate code any more for crates that will be run by Miri. So the LLVM backend does not have to implement the `miri_start_panic` intrinsic any more.

Fix minor error in `MaybeUninit::get_mut()` doc example
In the `MaybeUninit::get_mut()` example I wanted to assert that the slice was sorted and mistakenly used `.chunks(2)` rather than `.windows(2)` to assert it, as @ametisf pointed out in https://github.com/rust-lang/rust/pull/65948#issuecomment-589988183 .
This fixes it.
Relax str::get_unchecked precondition to permit empty slicing
Prior to this commit, `str` documented that `get_unchecked` had
the precondition that "`begin` must come before `end`". This would appear
to prohibit empty slices (i.e. begin == end).
In practice, get_unchecked is called often with empty slices. Let's relax
the precondition so as to allow them.

parse: unify item parsing & filter illegal item kinds
This PR fully unifies item parsing into a single `fn parse_item_common` method which produces `Option<Item>`. The `Item` is then mapped into `ForeignItem` and `AssocItem` as necessary by transforming the `*Kind` and converting contextually bad variants into `None`, thereby filtering them away.
The PR does not yet unmerge the definition of `ForeignItemKind` from `AssocItemKind`. I've left that as future work as it didn't feel like this parser-focused PR would be the best one to deal with it. Changes to the AST data structures are instead kept to a reasonable minimum.
Based on https://github.com/rust-lang/rust/pull/69361.
Fixes https://github.com/rust-lang/rust/issues/48137.
RELNOTES: Now, `item` macro fragments can be interpolated into `impl`, `trait`, and `extern` contexts. See `src/test/ui/parser/issue-48137-macros-cannot-interpolate-impl-items.rs` for the relevant test.

Split non macro portion of unused_doc_comment from macro part into two passes/lints
## Motivation
This change is motivated by the needs of the [spandoc library](https://github.com/yaahc/spandoc). The specific use case is that my macro is removing doc comments when an attribute is applied to a fn with doc comments, but I would like the lint to still appear when I forget to add the `#[spandoc]` attribute to a fn, so I don't want to have to silence the lint globally.
## Approach
This change splits the `unused _doc_comment` lint into two lints, `unused_macro_doc_comment` and `unused_doc_comment`. The non macro portion is moved into an `early_lint_pass` rather than a pre_expansion_pass. This allows proc macros to silence `unused_doc_comment` warnings by either adding an attribute to silence it or by removing the doc comment before the early_pass runs.
The `unused_macro_doc_comment` lint however will still be impossible for proc-macros to silence, but the only alternative that I can see is to remove this lint entirely, which I don't think is acceptable / is a decision I'm not comfortable making personally, so instead I opted to split the macro portion of the check into a separate lint so that it can be silenced globally with an attribute if necessary without needing to globally silence the `unused_doc_comment` lint as well, which is still desireable.

... my god it takes a long time to compile when you're on a cellular

Do not ping the infrastructure team on toolstate changes
To my knowledge, there is essentially never any particular action that the infra team needs to take on these pings, and they are currently relatively annoying.
cc rust-lang/infra -- does anyone *want* these notifications?
