Compare rvalue types in assertion

Because it is possible for the lowering process to change the flags,
this comparison check could trip when the types were, in fact equal,
but SIL lowering had optimized storage for the lowered type.

In the test case given, the SIL type had flags for Object storage while
the lowering type had flags for LocalStorage
