This leaves the `Share` trait at `std::kinds` via a `#[deprecated]` `pub use`

All code referencing the `Share` trait should now reference the `Sync` trait,

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.

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.

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.

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.

As discovered in #15460, a particular #[link(kind = "static", ...)] line is not
actually guaranteed to link the library at all. The reason for this is that if
the external library doesn't have any referenced symbols in the object generated
by rustc, the entire library is dropped by the linker.
For dynamic native libraries, this is solved by passing -lfoo for all downstream
compilations unconditionally. For static libraries in rlibs this is solved
because the entire archive is bundled in the rlib. The only situation in which
this was a problem was when a static native library was linked to a rust dynamic
library.
This commit brings the behavior of dylibs in line with rlibs by passing the
--whole-archive flag to the linker when linking native libraries. On OSX, this
uses the -force_load flag. This flag ensures that the entire archive is
considered candidate for being linked into the final dynamic library.
This is a breaking change because if any static library is included twice in the
same compilation unit then the linker will start emitting errors about duplicate
definitions now. The fix for this would involve only statically linking to a
library once.

Using the Show impl for Names created global symbols with names like
`"str\"str\"(1027)"`. This adjusts strings, binaries and vtables to
avoid using that impl.
Fixes#15799.
This is an alternative to upgrading the way rvalues are handled in the
borrow check. Making rvalues handled more like lvalues in the borrow
check caused numerous problems related to double mutable borrows and
rvalue scopes. Rather than come up with more borrow check rules to try
to solve these problems, I decided to just forbid pattern bindings after
`@`. This affected fewer than 10 lines of code in the compiler and
libraries.
This breaks code like:
match x {
y @ z => { ... }
}
match a {
b @ Some(c) => { ... }
}
Change this code to use nested `match` or `let` expressions. For
example:
match x {
y => {
let z = y;
...
}
}
match a {
Some(c) => {
let b = Some(c);
...
}
}

Our implementation of ebml has diverged from the standard in order
to better serve the needs of the compiler, so it doesn't make much
sense to call what we have ebml anyore. Furthermore, our implementation
is pretty crufty, and should eventually be rewritten into a format
that better suits the needs of the compiler. This patch factors out
serialize::ebml into librbml, otherwise known as the Really Bad
Markup Language. This is a stopgap library that shouldn't be used
by end users, and will eventually be replaced by something better.

Currently, each time a function is monomorphized, all items within that function are translated. This is unnecessary work because the inner items already get translated when the function declaration is visited by `trans_item`. This patch adds a flag to the `FunctionContext` to prevent translation of items during monomorphization.
Remove the ability of the borrow checker to determine that repeated
dereferences of a Box<T> refer to the same memory object. This will
usually require one of two workarounds:
1) The interior of a Box<T> will sometimes need to be moved / borrowed
into a temporary before moving / borrowing individual derived paths.
2) A `ref x` pattern will have to be replaced with a `box ref x`
pattern.
Fixes#16094.

Like with libnative, when a green task failed to spawn it would leave the world
in a corrupt state where the local scheduler had been dropped as well as the
local task. Also like libnative, this patch sets up a "bomb" which when it goes
off will restore the state of the world.
This adds support for `quote_arm!(cx, $pat => $expr)`, and `macro_rules!(($a:arm) => (...))`. It also fixes a bug in pretty printing, where this would generate invalid code:
```
match { 5i } {
1 => 2,
_ => 3,
}
```
It would generate this code:
```
match { 5i } {
1 => 2
_ => 3
}
```
Finally, it adds a couple helper methods to `ExtCtxt`.
When dealing with HTTP request or responses, many tokens are case-insensitive in the ASCII range but the bytes from the network are not necessarily valid UTF-8.
**[breaking-change]** Rather than adding new very similar traits, this re-uses the `std::ascii::OwnedStrAsciiExt` and `std::ascii::StrAsciiExt` traits, but rename to remove `Str` since that does not apply for bytes.
This PR also makes `std::ascii::ASCII_UPPER_MAP` and `std::ascii::ASCII_LOWER_MAP`, the lookup table all these methods are based on, public. In case there is something else related to ASCII case we haven’t thought of yet, that can be implemented outside of libstd without duplicating the tables.
Although this is a breaking change, I thought this could do without an RFC since the relevant traits are not in the prelude.
