This patch adds the ability to get a DWARFDIE's children as an LLVM range.

This way we can use for range loops to iterate over them and we can use
LLVM's algorithms like `llvm::all_of` to query all children.

The implementation has to do some small shenanigans as the iterator
needs to store a DWARFDIE, but a DWARFDIE container is also a DWARFDIE
so it can't return the iterator by value. I just made the `children` getter a
templated function to avoid the cyclic dependency.
