* compress wording of out-of-band content to avoid line-wrap as much as possible
Previously the implementation detection regex would detect
`impl fmt::Show for MyStruct` as `fmt`. Now it will be detected as
`fmt::Show for MyStruct`. Implementations such as `impl MyStruct` will
still be detected as `MyStruct`.
This commit stabilizes the `std::sync::atomics` module, renaming it to
`std::sync::atomic` to match library precedent elsewhere, and tightening
up behavior around incorrect memory ordering annotations.
The vast majority of the module is now `stable`. However, the
`AtomicOption` type has been deprecated, since it is essentially unused
and is not truly a primitive atomic type. It will eventually be replaced
by a higher-level abstraction like MVars.
Due to deprecations, this is a:
[breaking-change]
Generic extern functions written in Rust have their names mangled, as well as their internal clownshoe __rust_abi functions. This allows e.g. specific monomorphizations of these functions to be used as callbacks.
Closes#12502.
This teach rustdoc to add `<meta name="description">` and `<meta name="keywords">` tags to crate docs. Description is important for search engines because they display it as the page description. Keywords are less useful but still generally recommended.
This also changes the "stability dashboard" link to just say "stability", because the current link takes up a lot of space.

There's a good long comment explaining why. The tl;dr; is that I have no idea
why this is necessary, but it gets --test to work on windows which is something,
right?

This ended up passing through the lexer but dying later on in parsing when it
wasn't handled. The strategy taken was to copy the `str_lit` funciton, but adapt
it for bytes.

Fixes missing overflow lint for i64 #14269
The `type_overflow` lint, doesn't catch the overflow for `i64` because the overflow happens earlier in the parse phase when the `u64` as biggest possible int gets casted to `i64` , without checking the for
overflows.
We can't lint in the parse phase, so we emit a compiler error, as we do for overflowing `u64`
Perhaps a consistent behaviour would be to emit a parse error for *all* overflowing integer types.
See #14269
The reference manual said that code is interpreted as UTF-8 text and a implementation will normalize it to NFKC. However, rustc doesn't do any normalization now.
We may want to do any normalization for symbols, but normalizing whole text seems harmful because doing so loses some sort of information even if we choose a non-K variant of normalization.
I'd suggest removing "normalized to Unicode normalization form NFKC" phrase for the present so that the manual represents the current state properly. When we address the problem (with a RFC?), then the manual should be updated.
Closes#12388.

The `type_overflow` lint, doesn't catch the overflow for `i64` because
the overflow happens earlier in the parse phase when the `u64` as biggest
possible int gets casted to `i64` , without checking the for overflows.
We can't lint in the parse phase, so a refactoring of the `LitInt` type
was necessary.
The types `LitInt`, `LitUint` and `LitIntUnsuffixed` where merged to one
type `LitInt` which stores it's value as `u64`. An additional parameter was
added which indicate the signedness of the type and the sign of the value.
