Incorrect error: Cannot instantiate local class 'I.IInner' in a static context

This ticket is to cover some loose ends in how ECJ handles requirement (or not) of enclosing instances: (JLS 8.1.3)

The following should compile, but doesn't:

```
public class C {
void q() {
interface I {
class IInner {}
static void p() {
new IInner();
}
}
}
}
```

While working on https://github.com/eclipse-jdt/eclipse.jdt.core/pull/4020 for https://github.com/eclipse-jdt/eclipse.jdt.core/issues/4015 I noticed that the call site of

org.eclipse.jdt.internal.compiler.problem.ProblemReporter.allocationInStaticContext(ASTNode, LocalTypeBinding) in org.eclipse.jdt.internal.compiler.ast.ReferenceExpression.resolveType(BlockScope) resembles org.eclipse.jdt.internal.compiler.ast.AllocationExpression.resolveType(BlockScope) before https://github.com/eclipse-jdt/eclipse.jdt.core/pull/3699

Should the PR https://github.com/eclipse-jdt/eclipse.jdt.core/pull/3699 also have accounted for ReferenceExpressions ?
