- Support enums in C and ObjC as their
AST representations differ slightly.
- Add support for typedef'ed enums.

If the enum is a dependent type, we would crash somewhere in
getIntWidth(). -Wswitch diagnostic doesn't work on dependent enums
either.

If an enum has different names for the same constant, make sure only the first one declared gets added into the switch. Failing to do so results in a compiler error as 2 case labels can't represent the same value.
```
lang=c
enum Numbers{
One,
Un = One,
Two,
Deux = Two,
Three,
Trois = Three
};
// Old behaviour
switch (<Number>) {
case One:
case Un:
case Two:
case Duex:
case Three:
case Trois: break;
}
// New behaviour
switch (<Number>) {
case One:
case Two:
case Three: break;
}
```

It fixes the -Wswitch warning, though we mark it as a fix even if that is off.
This makes it the "recommended" action on an incomplete switch, which seems OK.

Intent was a nice idea but it ends up being a bit awkward/heavyweight
without adding much.
In particular, it makes it hard to implement `CodeActionParams.only` properly
(there's an inheritance hierarchy for kinds).

Improve the recently-added PopulateSwitch tweak to work on non-empty switches.

Add a tweak that populates an empty switch statement of an enumeration type with all of the enumerators of that type.
Before:
```
enum Color { RED, GREEN, BLUE };
void f(Color color) {
switch (color) {}
}
```
After:
```
enum Color { RED, GREEN, BLUE };
void f(Color color) {
switch (color) {
case RED:
case GREEN:
case BLUE:
break;
}
}
```
