[clang] Incorrect source range for explicit object calls when callee is pointer

[necto]

In Clang v20.1.7, the issue range for explicit object calls has been improved for . calls, but not for the -> calls. As you can observe on Compiler Explorer, the object is included in the range for the . calls, but for the -> call:

struct ExplicitThis {
  void member(this ExplicitThis const& self);
};

void test1(ExplicitThis* ptr, ExplicitThis& ref, ExplicitThis val) {
  ptr->member(); // Begin or CallExpr range is lost.
  ref.member(); // Improved range
  val.member(); // Improved range
}
