Member predicate VariableAccess::getQualifier

Gets the expression generating the variable being accessed.

As a few examples: For ptr->x, this gives ptr. For (*ptr).x, this gives (*ptr). For smart_ptr->x, this gives the call to operator->.

This applies mostly to FieldAccesses, but also to static member variables accessed “through” a pointer. Note that it does NOT apply to static member variables accessed through a type name, as in that case the type name is a qualifier on the variable rather than a qualifier on the access.
