4f15867faf bootstrap: Further centralize target defaulting logic.
Background: targets can be specied with or without config files;
unneccessarily differences in the logic between those cases has caused
a) the bug I tried to fix in the previous commit, b) the bug I
introduced in the previous commit.

The solution is to make the code paths the same as much as possible.

1. Targets are now not created from the `default` method. (I would both
remove the impl if this was a public library, but just wrap it for
convience becaues it's not.) Instead, there is a `from_triple` method
which does the defaulting.

2. Besides the sanity checking, use the new method in the code reading
config files. Now `no_std` is overriden iff set explicitly just like the
other fields which are optional in the TOML AST type.

3. In sanity checking, just populate the map for all targets no matter
what. That way do don't duplicate logic trying to be clever and remember
which targets have "non standard" overrides. Sanity checking is back to
just sanity checking, and out of the game of trying to default too.

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.

Add rustdoc aliases to `ptr::copy` and `ptr::copy_nonoverlapping`

This PR adds a [rustdoc alias](https://doc.rust-lang.org/nightly/rustdoc/unstable-features.html#add-aliases-for-an-item-in-documentation-search) to `ptr::copy` and `ptr::copy_nonoverlapping` using the commonly used terms `memcpy` and `memmove`. The motivation for this PR is to improve discoverability for these functions, since I've noticed users overlook these functions on multiple occasions (and they have thus reached for [libc](https://crates.io/crates/libc) without need). Currently std docs state:

https://doc.rust-lang.org/nightly/std/ptr/fn.copy_nonoverlapping.html
> `copy_nonoverlapping` is semantically equivalent to C's `memcpy`, but with the argument order swapped.

https://doc.rust-lang.org/nightly/std/ptr/fn.copy.html
> `copy` is semantically equivalent to C's `memmove`, but with the argument order swapped.

Rollup merge of - danielhenrymantilla:maybe_uninit_docs_replace_chunk_with_windows, r=Dylan-DPC
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.

Rollup merge of - ridiculousfish:relax_get_unchecked, r=nagisa
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.
