These are tests that fail in the next commit without this flag. This
does not add -verify-ignore-unrelated to all tests with -verify, only
the ones that would fail without it. This is NFC since this flag is
currently a no-op.
Some editors use diagnostics from SourceKit to replace build issues. This causes issues if the diagnostics from SourceKit are formatted differently than the build issues. Make sure they are rendered the same way, removing most uses of `DiagnosticsEditorMode`.
To do so, always emit the `add stubs for conformance` note (which previously was only emitted in editor mode) and remove all `; add <something>` suffixes from notes that state which requirements are missing.

* [TypeChecker] Enclosing stubs protocol note within editor mode
* [test] Removing note from test where there is no -diagnostics-editor-mode flag
* Formatting modified code
* [tests] Fixing tests under validation-tests
Under non-editor mode, the fixit for inserting protocol stubs is associated with a note
pointing to the missing protocol member declaration which could stay in a separate file from
the conforming type, leading to the behavior of rdar://51534405. This change checks if
the fixit is in a separate file and issues another note to carry the fixit if so.

Adjust the Parse/objc_enum test for Windows. Windows x64 is a LLp64 target,
which imports `Int` differently. Explicitly use `Int32` for the inheritance.
@objc enums have special requirements on the raw type, which were
enforced as part of checking the raw type of the enum. Rework the
checking here so that the additional constraints are part of resolving
whether the enum is exposed to Objective-C. This keeps raw-type
computation more independent and “lower-level” than @objc computation.
Once reworked, eliminate the “CIntegerTypes” cache from TypeChecker:
it probably doesn't matter, and the caching should be performed by the
request-evaluator rather than the type checker.
we would reject an invalid @objc enum with:
<unknown>:0: error: cannot assign value of type '(progress: Int) -> Status' to type 'Status'
because we were poking at the enum element before it was validated.
Inference of type witnesses for associated types was previously
implemented as part of value witness matching in the constraint
solver. This led to a number of serious problems, including:
- Recursion problems with the solver hunting for a type witness,
which triggers more attemts to match value witnesses...
- Arbitrarily crummy attempts to break the recursion causing
type-check failures in fun places.
- Ordering dependencies abound: different results depending on which
value witnesses were satisfied first, failures because of the order
in which we attempted to infer type witnesses, etc.
This new implementation of type witness inference uses a separate pass
that occurs whenever we're looking for any type witness, and solves
all of the type witnesses within a given conformance
simultaneously. We still look at potential value witnesses to infer
type witnesses, but we match them structurally, without invoking the
constraint solver.
There are a few caveats to this implementation:
* We're not currently able to infer type witnesses from value
witnesses that are global operators, so some tricks involving global
operators (*cough* ~> *cough*) might require some manually-specified
type witnesses. Note that the standard library doesn't include any
such cases.
* Yes, it's another kind of solver. At simple one, fortunately.
On the other hand, this implementation should be a big step forward:
* It's far more predictable, order-invariant, and non-recursive.
* The diagnostics for failures to infer type witnesses have
improved.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.
