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);
const TypeDecl *declParent =
