d3bd4abcbb [swiftc (40 vs. 5451)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 40 (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)`](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);
}

```

I saw this pass in one run, then fail in the next.

f2d159940c Sema: Fix corner case with @_fixed_layout diagnostic 
We allow a member of a type to be more accessible than the type
itself. In this case, the broader accessibility is ignored, and
the effective access of the member is constrained by the
accessibility of its parent type.

/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)`](5fe6f33ae5/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);
}

```

73771919d5 [swiftc (42 vs. 5433)] Add crasher in swift::constraints::ConstraintGraph::addConstraint(...) 
Add test case for crash triggered in `swift::constraints::ConstraintGraph::addConstraint(...)`.

Current number of unresolved compiler crashers: 42 (5433 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index"` added on 2013-12-09 by you in commit 11794095 :-)

Assertion failure in [`lib/Sema/ConstraintGraph.cpp (line 50)`](de771d3819/lib/Sema/ConstraintGraph.cpp (L50)):

```
Assertion `impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index"' failed.

When executing: std::pair<ConstraintGraphNode &, unsigned int> swift::constraints::ConstraintGraph::lookupNode(swift::TypeVariableType *)
```

Assertion context:

```c++
std::pair<ConstraintGraphNode &, unsigned>
ConstraintGraph::lookupNode(TypeVariableType *typeVar) {
  // Check whether we've already created a node for this type variable.
  auto &impl = typeVar->getImpl();
  if (auto nodePtr = impl.getGraphNode()) {
    assert(impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index");
    assert(TypeVariables[impl.getGraphIndex()] == typeVar &&
           "Type variable mismatch");
    return { *nodePtr, impl.getGraphIndex() };
  }

55c0e7401c Sema: Fix crash when @noescape or @autoclosure is applied to parameter 
In Swift 3, these attributes were changed to apply to the type,
and not the parameter. If they appear on the parameter, we would
go down a diagnostic code path.

When checking a generic function signature, we might not have a
contextual type for the parameter yet, so bail out instead of
crashing.

8c956c6f07 Disable a compiler_crasher test that is non-deterministic. 
The 28616-swift-parser-parseexprsequence-swift-diag-bool-bool.swift test
crashes due to a stack overflow. I had previously disabled it to get
through a master-next merge, so this just leaves it disabled. The only
change is to replace the Radar number with a better reason for why it is
disabled.
