ff261d3a6b Auto merge of #38097 - Mark-Simulacrum:fn-sig-slice, r=eddyb
Refactor ty::FnSig to contain a &'tcx Slice<Ty<'tcx>>

We refactor this in order to achieve the following wins:

 - Decrease the size of `FnSig` (`Vec` + `bool`: 32, `&Slice` + `bool`: 24).
 - Potentially decrease total allocated memory due to arena-allocating `FnSig` inputs/output; since they are allocated in the type list arena, other users of type lists can reuse the same allocation for an equivalent type list.
 - Remove the last part of the type system which needs drop glue (#37965 removed the other remaining part). This makes arenas containing `FnSig` faster to drop (since we don't need to drop a Vec for each one), and makes reusing them without clearing/dropping potentially possible.

Point arg num mismatch errors back to their definition

This PR updates the arg num errors (like E0061) to point back at the function definition where they were defined.

Before:

```
error[E0061]: this function takes 2 parameters but 1 parameter was supplied
  --> E0061.rs:18:7
   |
18 |     f(0);
   |       ^
   |
   = note: the following parameter types were expected:
   = note: u16, &str
```

Now:

```
error[E0061]: this function takes 2 parameters but 1 parameter was supplied
  --> E0061.rs:18:7
   |
11 | fn f(a: u16, b: &str) {}
   | ------------------------ defined here
...
18 |     f(0);
   |       ^ expected 2 parameters
```

This is an incremental improvement.  We probably want to underline only the function name and also have support for functions defined in crates outside of the current crate.

ebeee0e27e Auto merge of #38092 - pnkfelix:mir-stats, r=nikomatsakis
Adds `-Z mir-stats`, which is similar to `-Z hir-stats`.

Adds `-Z mir-stats`, which is similar to `-Z hir-stats`.

Some notes:

* This code attempts to present the breakdown of each variant for
  every enum in the MIR. This is meant to guide decisions about how to
  revise representations e.g. when to box payloads for rare variants
  to shrink the size of the enum overall.

* I left out the "Total:" line that hir-stats presents, because this
  implementation uses the MIR Visitor infrastructure, and the memory
  usage of structures directly embedded in other structures (e.g. the
  `func: Operand` in a `TerminatorKind:Call`) is not distinguished
  from similar structures allocated in a `Vec` (e.g. the `args:
  Vec<Operand>` in a `TerminatorKind::Call`). This means that a naive
  summation of all the accumulated sizes is misleading, because it
  will double-count the contribution of the `Operand` of the `func` as
  well as the size of the whole `TerminatorKind`.

  * I did consider abandoning the MIR Visitor and instead hand-coding
    a traversal that distinguished embedded storage from indirect
    storage. But such code would be fragile; better to just require
    people to take care when interpreting the presented results.

* This traverses the `mir.promoted` rvalues to capture stats for MIR
  stored there, even though the MIR visitor super_mir method does not
  do so. (I did not observe any promoted mir being newly traversed when
  compiling the rustc crate, however.)

* It might be nice to try to unify this code with hir-stats.  Then
  again, the reporting portion is the only common code (I think), and
  it is small compared to the visitors in hir-stats and mir-stats.

in region, treat current (and future) item-likes alike

The `visit_fn` code mutates its surrounding context.  Between *items*,
this was saved/restored, but between impl items it was not. This meant
that we wound up with `CallSiteScope` entries with two parents (or
more!).  As far as I can tell, this is harmless in actual type-checking,
since the regions you interact with are always from at most one of those
branches. But it can slow things down.

Before, the effect was limited, since it only applied to impl items
within an impl. After #37660, impl items are visisted all together at
the end, and hence this could create a very messed up
hierarchy. Isolating impl item properly solves both issues.

I cannot come up with a way to unit-test this; for posterity, however,
you can observe the messed up hierarchies with a test as simple as the
following, which would create a callsite scope with two parents both
before and after

```
struct Foo {
}

impl Foo {
    fn bar(&self) -> usize {
        22
    }

    fn baz(&self) -> usize {
        22
    }
}

fn main() { }
```

Fixes #37864.
