ba13a894c0 Fixed crasher 28707 
The @_versioned accessibility check is done against the formal access. But the diagnostics is printed with getAccessForDiagnostics. In cases where the effective access is internal, the diagnostics will crash. Example:

```
class A { // implicitly internal
    @_versioned public var a: Int = 0 // explicity public
}
```

1367b0cb36 Invalidate default argument exprs if typechecking fails 
If typechecking fails, the expression will have unsolved type variables
written into it.  This Crashes The Compiler.

In that case, there’s no reason to keep a tree of dangling references
around.  Detach the initializer expression from the AST, but continue
to typecheck it to see if we can get some useful diagnostics out of it.

e3d7ff954e [swiftc (74 vs. 5456)] Add crasher in swift::MetatypeType::get 
Add test case for crash triggered in `swift::MetatypeType::get`.

Current number of unresolved compiler crashers: 74 (5456 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 362)`](8c0e9d5525/lib/AST/ASTContext.cpp (L362)):

```
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");
  }

```

practicalswift
c1ad56f53f [swiftc (67 vs. 5458)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 67 (5458 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 1168)`](9a6f2ba0e5/lib/AST/Type.cpp (L1168)):

```
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);
}

```

f41b3c4b6b [swiftc (55 vs. 5458)] Add crasher in swift::TypeChecker::resolveTypeInContext 
Add test case for crash triggered in `swift::TypeChecker::resolveTypeInContext`.

Current number of unresolved compiler crashers: 55 (5458 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `false && "Should have found context by now"` added on 2016-12-06 by you in commit fdaa88606 :-)

Assertion failure in [`lib/Sema/TypeCheckType.cpp (line 358)`](d352652a72/lib/Sema/TypeCheckType.cpp (L358)):

```
Assertion `false && "Should have found context by now"' failed.

When executing: std::tuple<DeclContext *, NominalTypeDecl *, bool> findDeclContextForType(swift::TypeChecker &, swift::TypeDecl *, swift::DeclContext *, TypeResolutionOptions)
```

Assertion context:

```c++
    // or associated type from a context outside a ProtocolDecl.
    if (isa<ProtocolDecl>(parentDC) && isa<AbstractTypeParamDecl>(typeDecl))
      return std::make_tuple(nullptr, nullptr, false);
  }

  assert(false && "Should have found context by now");
  return std::make_tuple(nullptr, nullptr, false);
}

the subject is Self. Gather the list from there rather than separately
computing/storing the list of "inherited protocols".

f1f9e88360 Cache expression types in failure diagnosis. 
After we call into typeCheckExpression() we need to cache the
resulting types in the constraint system type map because we later
call into code that reads the types out of the type map.

Fixes rdar://problem/30376186 as well as a couple crashers.

4ffb4a443f [swiftc (52 vs. 5454)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 52 (5454 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 1304)`](ee4100ca8a/lib/AST/Type.cpp (L1304)):

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

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

Assertion context:

```c++
    break;
  }
  }

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

```
