4032b85aec Auto merge of #21278 - thchittenden:issue-21033-struct-var-pattern-fix, r=alexcrichton 
Closes #21033. The new strategy for parsing a field pattern is to look 1 token ahead and if it's a colon, parse as "fieldname: pat", otherwise parse the shorthand form "(box) (ref) (mut) fieldname)". The previous strategy was to parse "(ref) (mut) fieldname" then if we encounter a colon, throw an error if either "ref" or "mut" were encountered.

dcaeb6aa23 auto merge of #20901 : dgrunwald/rust/update-token-can-begin-expr, r=sanxiyn 
* add `Token::AndAnd` (double borrow)
 * add `Token::DotDot` (range notation)
 * remove `Token::Pound` and `Token::At`

This fixes a syntax error when parsing `fn f() -> RangeTo<i32> { return ..1; }`.

Also, remove `fn_expr_lookahead`.
It's from the `fn~` days and seems to no longer be necessary.

44440e5c18 core: split into fmt::Show and fmt::String 
fmt::Show is for debugging, and can and should be implemented for
all public types. This trait is used with `{:?}` syntax. There still
exists #[derive(Show)].

fmt::String is for types that faithfully be represented as a String.
Because of this, there is no way to derive fmt::String, all
implementations must be purposeful. It is used by the default format
syntax, `{}`.

This will break most instances of `{}`, since that now requires the type
to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the
correct fix. Types that were being printed specifically for users should
receive a fmt::String implementation to fix this.

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
