5020d92341 [swiftc (45 vs. 5390)] Add crasher in swift::Expr::walk(...) 
Add test case for crash triggered in `swift::Expr::walk(...)`.

Current number of unresolved compiler crashers: 45 (5390 resolved)

/cc @jrose-apple - just wanted to let you know that this crasher caused an assertion failure for the assertion `VD->getDeclContext()->isModuleScopeContext()` added on 2015-07-17 by you in commit 5c71b75b :-)

Assertion failure in [`lib/Sema/MiscDiagnostics.cpp (line 565)`](https://github.com/apple/swift/blob/master/lib/Sema/MiscDiagnostics.cpp#L565):

```
Assertion `VD->getDeclContext()->isModuleScopeContext()' failed.

When executing: void diagSyntacticUseRestrictions(swift::TypeChecker &, const swift::Expr *, const swift::DeclContext *, bool)::DiagnoseWalker::checkUnqualifiedAccessUse(const swift::DeclRefExpr *)
```

Assertion context:

```
          if (!ignoredBase->isImplicit())
            return;
        }
        if (auto *calledBase = dyn_cast<DotSyntaxCallExpr>(parentExpr)) {
          if (!calledBase->isImplicit())
            return;
        }
      }

      const auto *VD = cast<ValueDecl>(D);

36c63d55d3 [swiftc (43 vs. 5390)] Add crasher in swift::TypeChecker::lookupConstructors 
Add test case for crash triggered in `swift::TypeChecker::lookupConstructors`.

Current number of unresolved compiler crashers: 43 (5390 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `type->mayHaveMembers()` added on 2017-01-02 by you in commit 18adb532 :-)

Assertion failure in [`lib/Sema/TypeCheckNameLookup.cpp (line 255)`](https://github.com/apple/swift/blob/master/lib/Sema/TypeCheckNameLookup.cpp#L255):

```
Assertion `type->mayHaveMembers()' failed.

When executing: swift::LookupResult swift::TypeChecker::lookupMember(swift::DeclContext *, swift::Type, swift::DeclName, NameLookupOptions)
```

Assertion context:

```
}

LookupResult TypeChecker::lookupMember(DeclContext *dc,
                                       Type type, DeclName name,

Add test case for crash triggered in `swift::TypeChecker::resolveDeclRefExpr`.

Current number of unresolved compiler crashers: 30 (5390 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `hasInterfaceType() && "No interface type was set"` added on 2016-12-04 by you in commit c1a21613 :-)

Assertion failure in [`lib/AST/Decl.cpp (line 1678)`](https://github.com/apple/swift/blob/master/lib/AST/Decl.cpp#L1678):

```
Assertion `hasInterfaceType() && "No interface type was set"' failed.

When executing: swift::Type swift::ValueDecl::getInterfaceType() const
```

Assertion context:

```
bool ValueDecl::hasInterfaceType() const {
  return !TypeAndAccess.getPointer().isNull();
}

Type ValueDecl::getInterfaceType() const {
  assert(hasInterfaceType() && "No interface type was set");
  return TypeAndAccess.getPointer();
}

void ValueDecl::setInterfaceType(Type type) {
  // lldb creates global typealiases with archetypes in them.
```

12cbf5d379 [swiftc (22 vs. 5389)] Add crasher in swift::IterativeTypeChecker::satisfy(...) 
Add test case for crash triggered in `swift::IterativeTypeChecker::satisfy(...)`.

Current number of unresolved compiler crashers: 22 (5389 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `isSatisfied(request)` added on 2015-10-09 by you in commit b49964e3 :-)

Assertion failure in [`lib/Sema/IterativeTypeChecker.cpp (line 107)`](https://github.com/apple/swift/blob/master/lib/Sema/IterativeTypeChecker.cpp#L107):

```
Assertion `isSatisfied(request)' failed.

When executing: void swift::IterativeTypeChecker::satisfy(swift::TypeCheckRequest)
```

Assertion context:

```
      return true;
    });

    // If there were no unsatisfied dependencies, we're done.
    if (unsatisfied.empty()) {
      assert(isSatisfied(request));
      break;
    }

    // Recurse to satisfy any unsatisfied dependencies.
    // FIXME: Don't recurse in the iterative type checker, silly!
```
