[Clang] Incomplete/incorrect code completion about explicit object member function

[zwuis]

Godbolt: https://godbolt.org/z/EPaebdEx9

struct S {
  void foo1() const;
  void foo2();
  void foo3(this const S& self);
  void foo4(this S& self);
};

void S::foo1() const {
  this-> // #1
}

void S::foo2() {
  this-> // #2
}

void S::foo3(this const S& self) {
  self. // #3
}

void S::foo4(this S& self) {
  self. // #4
}

void test1(S s) {
  s. // #5
}

void test2(const S s) {
  s. // #6
}

Code completion results:

At #1, #3 and #6: (missing foo3)

COMPLETION: foo1 : [#void#]foo1()[# const#]
COMPLETION: S : S::

---

At #2, #4 and #5: (unexpected argument in foo3 and foo4)

COMPLETION: foo1 : [#void#]foo1()[# const#]
COMPLETION: foo2 : [#void#]foo2()
COMPLETION: foo3 : [#void#]foo3(<#const S &self#>)
COMPLETION: foo4 : [#void#]foo4(<#S &self#>)
COMPLETION: operator= : [#S &#]operator=(<#const S &#>)
COMPLETION: operator= : [#S &#]operator=(<#S &&#>)
COMPLETION: S : S::
COMPLETION: ~S : [#void#]~S()
