[cfe-commits] Patch: Add warning for variable initialization that references the value of itself

[Chandler Carruth]

Thanks Richard. I've committed this after making a few tweaks in r128376.

For reference, the tweaks I made were:
- Moved under -Wuninitialized and grouped the warning appropriately for that
- Slightly tweaked the wording to flow better and match existing
uninitialized warnings' wording
- Only underline the identifier rather than the entire declaration. I think
this looks a bit better and should avoid issues in cases like:

int x, y = y + 2;

- Some formatting tweaks here and there.
