Use `Ident`s for fields in HIR
Continuation of https://github.com/rust-lang/rust/pull/49718, part of https://github.com/rust-lang/rust/issues/49300

This commit updates the `Mac_` AST structure to keep track of the delimiters
that it originally had for its invocation. This allows us to faithfully
pretty-print macro invocations not using parentheses (e.g. `vec![...]`). This in
turn helps procedural macros due to #43081.
Closes #50840

Implement label break value (RFC 2046)

Implements RFC 1576.
See: https://github.com/rust-lang/rfcs/blob/master/text/1576-macros-literal-matcher.md
Changes are mostly in libsyntax, docs, and tests. Feature gate is
enabled for 1.27.0.
Many thanks to Vadim Petrochenkov for following through code reviews
and suggestions.
Example:
````rust
macro_rules! test_literal {
($l:literal) => {
println!("literal: {}", $l);
};
($e:expr) => {
println!("expr: {}", $e);
};
}
fn main() {
let a = 1;
test_literal!(a);
test_literal!(2);
test_literal!(-3);
}
```
Output:
```
expr: 1
literal: 2
literal: -3
```

Implement tool_attributes feature (RFC 2103)
cc #44690
This is currently just a rebased and compiling (hopefully) version of #47773.
Let's see if travis likes this. I will add the implementation for `tool_lints` this week.

Use escape_default() for strings in LitKind::token().
This avoids converting every char to \u{...} form, which bloats the
resulting strings unnecessarily. It also provides consistency with the
existing escape_default() calls in LitKind::token() used for raw
string literals, char literals, and raw byte char literals.
There are two benefits from this change.
- Compilation is faster. Most of the rustc-perf benchmarks see a
non-trivial speedup, particularly for incremental rebuilds, with the
best speedup over 13%, and multiple others over 10%.
- Generated rlibs are smaller. An extreme example is libfutures.rlib,
which shrinks from 2073306 bytes to 1765927 bytes, a 15% reduction.

This speeds up numerous rust-perf benchmark runs, by up to 3%.

Change the hashcounts in raw `Lit` variants from usize to u16.
This reduces the size of `Token` from 32 bytes to 24 bytes on 64-bit
platforms.

Expand macros in `extern {}` blocks
This permits macro and proc-macro and attribute invocations (the latter only with the `proc_macro` feature of course) in `extern {}` blocks, gated behind a new `macros_in_extern` feature.
