[clang] Parenthesized initialization of arrays does not work in new expression

[tomasz-kaminski-sonarsource]

The parenthesized initialization of arrays (aggregates) is not supported in the new expression:

int main() {
  int x[10](1, 2);  // OK
  auto p = new int[10](1, 2); // ERROR, accepted by GCC and MSVC
}

Live example: Godbolt
