`M0-1-9`: Wrong dead code detection on function templates

[nbusser]

Affected rules

• M0-1-9

Description

When using template type, some irrelevant M0-1-9 warnings are triggered

Example

template <typename T>
void false_positive() {
  T t;
  std::cin >> t; // Triggers M0-1-9
}

template <typename T>
void true_negative() {
  std::uint32_t u32;
  std::cin >> u32;
}
