  Log Message:
  -----------
  [clang] Add -Wuninitialized-const-pointer (#148337)

This option is similar to -Wuninitialized-const-reference, but diagnoses
the passing of an uninitialized value via a const pointer, like in the
following code:
```
void foo(const int *);
void test() {
  int v;
  foo(&v);
}
```
