0431134119 Remove the explicit closure kind syntax from the parser and AST; 
upgrade the inference based on expected type so that it is able to
infer the fn kind in isolation even if the full signature is not
available (and we could perhaps do better still in some cases, such as
extracting just the types of the arguments but not the return value).

07cdb85331 Move return type an associated type of the Fn* traits. Mostly this involves tweaking things in 
the compiler that assumed two input types to assume two ouputs; we also have to teach `project.rs`
to project `Output` from the unboxed closure and fn traits.

0c981875e4 rollup merge of #21340: pshc/libsyntax-no-more-ints 
Collaboration with @rylev!

I didn't change `int` in the [quasi-quoter](99ae1a30f3/src/libsyntax/ext/quote.rs (L328)), because I'm not sure if there will be adverse effects.

Addresses #21095.

677b7cad3d Reformat metadata for exported macros 
Instead of copy-pasting the whole macro_rules! item from the original .rs file,
we serialize a separate name, attributes list, and body, the latter as
pretty-printed TTs.  The compilation of macro_rules! macros is decoupled
somewhat from the expansion of macros in item position.

This filters out comments, and facilitates selective imports.

bf6c007760 Change & pat to only work with &T, and &mut with &mut T. 
This implements RFC 179 by making the pattern `&<pat>` require matching
against a variable of type `&T`, and introducing the pattern `&mut
<pat>` which only works with variables of type `&mut T`.

The pattern `&mut x` currently parses as `&(mut x)` i.e. a pattern match
through a `&T` or a `&mut T` that binds the variable `x` to have type
`T` and to be mutable. This should be rewritten as follows, for example,

    for &mut x in slice.iter() {

becomes

    for &x in slice.iter() {
        let mut x = x;

Due to this, this is a

[breaking-change]

Closes #20496.

4e2afb0052 Remove ExprSlice by hacking the compiler 
[breaking-change]

The `mut` in slices is now redundant. Mutability is 'inferred' from position. This means that if mutability is only obvious from the type, you will need to use explicit calls to the slicing methods.

5e5cc6749e Slash the ast::Stmt type from 104 to 24 bytes. 
(on platforms with 64-bit pointers.)

The StmtMac variant is rather large and also fairly rare, so let's
optimise the common case.

ddb2466f6a librustc: Always parse macro!()/macro![] as expressions if not 
followed by a semicolon.

This allows code like `vec![1i, 2, 3].len();` to work.

This breaks code that uses macros as statements without putting
semicolons after them, such as:

    fn main() {
        ...
        assert!(a == b)
        assert!(c == d)
        println(...);
    }

It also breaks code that uses macros as items without semicolons:

    local_data_key!(foo)

    fn main() {
        println("hello world")
    }

Add semicolons to fix this code. Those two examples can be fixed as
follows:

    fn main() {
        ...
        assert!(a == b);
        assert!(c == d);
        println(...);
    }

    local_data_key!(foo);

    fn main() {
        println("hello world")
    }

RFC #378.

Closes #18635.
