13e9b3deb4 Deduplicate closure type errors 
Closure typing obligations flow in both direcitons to properly infer
types. Because of this, we will get 2 type errors whenever there's
an unfulfilled obligation. To avoid this, we deduplicate them in the
`InferCtxt`.

d540d44c71 Remove global_tcx from TyCtxt 
The non-global context was removed; there's only one context now. This
is a noop method that only serves to confuse readers -- remove it.

3eae7f6291 Upgrade to ena-0.13.1 and use the new inlined_probe_value function. 
This is a big speed win for `keccak` and `inflate`.

acf7d4dcdb Specialize the stalled_on handling in process_obligation(). 
Optimizing for the common numbers of entries in `stalled_on` wins about
4% on `keccak` and `inflate`.

3b85597d22 Add a specialized version of shallow_resolve(). 
The super-hot call site of `inlined_shallow_resolve()` basically does
`r.inlined_shallow_resolve(ty) != ty`. This commit introduces a
version of that function specialized for that particular call pattern,
`shallow_resolve_changed()`. Incredibly, this reduces the instruction
count for `keccak` by 5%.

The commit also renames `inlined_shallow_resolve()` as
`shallow_resolve()` and removes the `inline(always)` annotation, as it's
no longer nearly so hot.

7f0637da51 Shrink SubregionOrigin. 
It's currently 120 bytes on x86-64, due to one oversized variant
(`Subtype`). This commit boxes `Subtype`'s contents, reducing the size
of `SubregionOrigin` to 32 bytes.

The change speeds things up by avoiding lots of `memcpy` calls, mostly
relating to `RegionConstraintData::constraints`, which is a `BTreeMap`
with `SubregionOrigin` values.

Rollup merge of #62055 - matthewjasper:fix-error-counting, r=pnkfelix 
Fix error counting

Count duplicate errors for `track_errors` and other error counting checks.
Add FIXMEs to make it clear that we should be moving away from this kind of logic.

740668dbd9 Auto merge of #57428 - alexreg:associated_type_bounds, r=nikomatsakis,Centril 
Implementation of RFC 2289 (associated_type_bounds)

This PR implements the [`asociated_type_bounds` feature](https://github.com/rust-lang/rfcs/blob/master/text/2289-associated-type-bounds.md).

Associated type bounds are implemented in:
   - function/method arguments and return types
   - structs, enums, unions
   - associated items in traits
   - type aliases
   - type parameter defaults
   - trait objects
   - let bindings
