b976d9e666 Implement JSON error emission 
[breaking-change]

syntax::errors::Handler::new has been renamed to with_tty_emitter

Many functions which used to take a syntax::errors::ColorConfig, now take a rustc::session::config::ErrorOutputType. If you previously used ColorConfig::Auto as a default, you should now use ErrorOutputType::default().

It would be nice to backport this to beta, since this is the first release where this is true. I try really hard to not do doc backports, but this isn't very large, and might be worth making an exception, I dunno.

82c43432e0 modify trait checker to track the variables on which trait resolution is 
stalled rather than keeping this annoying mark; I checked that the
original compile-time regression that the mark was intended to
fix (https://github.com/rust-lang/rust/issues/18208) was still
reasonable, but I've not done exhaustive measurements to see how
important this "optimization" really is anymore

acc9428c6a Display better snippet for invalid char literal 
Given this code:

    fn main() {
        let _ = 'abcd';
    }

The compiler would give a message like:

    error: character literal may only contain one codepoint: ';
    let _ = 'abcd';
                 ^~

With this change, the message now displays:

    error: character literal may only contain one codepoint: 'abcd'
    let _ = 'abcd'
            ^~~~~~

1246f43bf9 Rollup merge of #30863 - jseyfried:no_rc, r=eddyb 
Use arena allocation instead of reference counting for `Module`s to fix memory leaks from `Rc` cycles.

A module references its module children and its import resolutions, and an import resolution references the module defining the imported name, so there is a cycle whenever a module imports something from an ancestor module.

For example,
```rust
mod foo { // `foo` references `bar`.
    fn baz() {}
    mod bar { // `bar` references the import.
        use foo::baz; // The import references `foo`.
    }
}
```

e51de045ef Rollup merge of #30851 - jonas-schievink:unneeded-dropflags, r=pnkfelix 
Apparently we allocate and maintain non-working dropflag hints since June... In anticipation of a working implementation of on-stack drop flag hints, let's not spend even more time on types that don't even need to be dropped.

```rust
fn main() {
    let (i,j,k,l) = (0,0,0,0);
}
```
used to translate to (unoptimized only, of course):
```llvm
define internal void @_ZN4main20ha8deb085c47920d8eaaE() unnamed_addr #0 {
entry-block:
  %dropflag_hint_10 = alloca i8
  %dropflag_hint_11 = alloca i8
  %dropflag_hint_12 = alloca i8
  %dropflag_hint_13 = alloca i8
  %const = alloca { i32, i32, i32, i32 }
  %i = alloca i32
  %j = alloca i32
  %k = alloca i32
  %l = alloca i32
  store i8 61, i8* %dropflag_hint_10
  store i8 61, i8* %dropflag_hint_11
  store i8 61, i8* %dropflag_hint_12
  store i8 61, i8* %dropflag_hint_13
  %0 = bitcast { i32, i32, i32, i32 }* %const to i8*
  call void @llvm.memcpy.p0i8.p0i8.i64(i8* %0, i8* bitcast ({ i32, i32, i32, i32 }* @const2752 to i8*), i64 16, i32 4, i1 false)
  %1 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 0
  %2 = load i32, i32* %1, align 4
  store i32 %2, i32* %i, align 4
  %3 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 1
  %4 = load i32, i32* %3, align 4
  store i32 %4, i32* %j, align 4
  %5 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 2
  %6 = load i32, i32* %5, align 4
  store i32 %6, i32* %k, align 4
  %7 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 3
  %8 = load i32, i32* %7, align 4
  store i32 %8, i32* %l, align 4
  ret void
}
```

Now it gives:
```llvm
define internal void @_ZN4main20ha8deb085c47920d8eaaE() unnamed_addr #0 {
entry-block:
  %const = alloca { i32, i32, i32, i32 }
  %i = alloca i32
  %j = alloca i32
  %k = alloca i32
  %l = alloca i32
  %0 = bitcast { i32, i32, i32, i32 }* %const to i8*
  call void @llvm.memcpy.p0i8.p0i8.i64(i8* %0, i8* bitcast ({ i32, i32, i32, i32 }* @const2748 to i8*), i64 16, i32 4, i1 false)
  %1 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 0
  %2 = load i32, i32* %1, align 4
  store i32 %2, i32* %i, align 4
  %3 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 1
  %4 = load i32, i32* %3, align 4
  store i32 %4, i32* %j, align 4
  %5 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 2
  %6 = load i32, i32* %5, align 4
  store i32 %6, i32* %k, align 4
  %7 = getelementptr inbounds { i32, i32, i32, i32 }, { i32, i32, i32, i32 }* %const, i32 0, i32 3
  %8 = load i32, i32* %7, align 4
  store i32 %8, i32* %l, align 4
  ret void
}
```

Let's hope I didn't break anything!
