db4e50a2f4 [swiftc (45 vs. 5451)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 45 (5451 resolved)

/cc @lattner - just wanted to let you know that this crasher caused an assertion failure for the assertion `Result && "Case not implemented!"` added on 2011-03-22 by you in commit fd2bf74f :-)

Assertion failure in [`lib/AST/Type.cpp (line 1299)`](72f7beead6/lib/AST/Type.cpp (L1299)):

```
Assertion `Result && "Case not implemented!"' failed.

When executing: swift::CanType swift::TypeBase::getCanonicalType()
```

Assertion context:

```c++
    SmallVector<Type, 4> CanGenericArgs;
    for (Type Arg : BGT->getGenericArgs())
      CanGenericArgs.push_back(Arg->getCanonicalType());
    Result = BoundGenericType::get(BGT->getDecl(), parentTy, CanGenericArgs);
    break;
  }
  }

  // Cache the canonical type for future queries.
  assert(Result && "Case not implemented!");
```

898940c2dd Extensions of imported classes never provide overriding initializers. (#7284) 
This addresses a crash where the compiler asks if an imported class
inherits initializers from its superclass /during the SIL passes/. In
this particular arrangement of subclasses and initializers (see test
case), this leads to us importing members of an Objective-C class for
the first time well after we've destroyed the type checker, and then
checking to see if an initializer added in a Swift extension can
prevent initializer inheritance. That initializer hasn't been
type-checked (because it's in another file and isn't supposed to
affect anything), and so the compiler chokes. A spot fix would merely
check for 'resolver' here and skip over the initializer if it doesn't
have a type, but it's not clear what the right semantics are in that
case.

The real issue here is that we don't support importing new declarations
after the type checker has been torn down, and that keeps causing us
problems, but that's a much bigger thing to fix.

/cc @lattner - just wanted to let you know that this crasher caused an assertion failure for the assertion `Result && "Case not implemented!"` added on 2011-03-22 by you in commit fd2bf74f :-)

Assertion failure in [`lib/AST/Type.cpp (line 1299)`](efc870a2d9/lib/AST/Type.cpp (L1299)):

```
Assertion `Result && "Case not implemented!"' failed.

When executing: swift::CanType swift::TypeBase::getCanonicalType()
```

Assertion context:

```c++
  }
  }

  // Cache the canonical type for future queries.
  assert(Result && "Case not implemented!");
  CanonicalType = Result;
  return CanType(Result);
}

37774eb97e Fix the TypeChecker's omitNeedlessWords to use interface types. (#7193) 
...avoiding a crash when trying to detect near misses of protocol
requirements. Unfortunately I can't come up with a test case for the
VarDecl changes; everything I try seems to already work. But using
interface types is more correct anyway.

4fd1ccfe43 [swiftc (38 vs. 5451)] Add crasher in swift::MetatypeType::get 
Add test case for crash triggered in `swift::MetatypeType::get`.

Current number of unresolved compiler crashers: 38 (5451 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `CurrentConstraintSolverArena && "No constraint solver active?"` added on 2012-11-14 by you in commit 2183b57fa :-)

Assertion failure in [`lib/AST/ASTContext.cpp (line 358)`](c2775070e2/lib/AST/ASTContext.cpp (L358)):

```
Assertion `CurrentConstraintSolverArena && "No constraint solver active?"' failed.

When executing: swift::ASTContext::Implementation::Arena &swift::ASTContext::Implementation::getArena(swift::AllocationArena)
```

Assertion context:

```c++
    switch (arena) {
    case AllocationArena::Permanent:
      return Permanent;

    case AllocationArena::ConstraintSolver:
      assert(CurrentConstraintSolverArena && "No constraint solver active?");
      return *CurrentConstraintSolverArena;
    }
    llvm_unreachable("bad AllocationArena");
  }

```

efb1ea4701 [bug-reducer] Disable bug reducer when the CMAKE_GENERATOR used is not Ninja. 
The bug reducer makes assumptions about the layout of the swift build directory
that may not be true in non-Ninja builds. Two examples of cmake generators that
would cause problems are VisualStudio and Xcode. I do not have time right now to
add such support, hence the disabling of the test.

1a2687a72e [Foundation] Convert Data’s SubSequence type to be Data 
Data can encapsulate it’s own sub-sequence type by housing a range of the slice in the structural type for Data. By doing this it avoids the API explosion of supporting all APIs that take Data would need overloads to take a slice of Data. This does come at a small conceptual cost: any index based iteration should always account for the startIndex and endIndex of the Data (which was an implicit requirement previously by being a Collection). Moreover this prevents the requirement of O(n) copies of Data if it is never mutated while parsing sub sequences; so more than an API amelioration this also could offer a more effecient code-path for applications to use.

It would be better to just ban @objc on deinit altogether, but it
was accepted in Swift 3.0.

For some reason we weren't desugaring the base type, so the
metatype check would fail.

45a19ddf2d Sema: Fix assertion failures with UnresolvedType in diagnostics 
We sometimes construct DependentMemberTypes with an UnresolvedType
base. These are not "real" interface types and can end up in
places where we don't expect interface types, triggering an
assertion. Make sure such types don't respond true to hasTypeParameter().
