Hover over variable (esp. a constant) could show its initial value

[HighCommander4]

In the following code:

#include <iostream>
constexpr int ANSWER = 42;
int main() {
  std::cout << ANSWER;
}

hovering over the use of ANSWER in main() shows const int ANSWER. It would be useful if the hover also included the value.

It now displays constexpr int ANSWER = 42; for literal const-qualified types (it will not expand type aliases)

Enumerators are now shown as Foo::A = 0
