[Bug c++/34772] -Winit-self ignored when compiling C++ (and ObjC++)

If by "delete this option from the C++ FE" you mean that `g++ -Winit-self
[...]' would give an error, I'm not sure that's the best approach if the option
is likely to be sorted out for C++ in the future.  Removing it now will break
existing makefiles which use -Winit-self for C++ compilations.  And once
-Winit-self is sorted out for C++, it will be harder to write a makefile which
gives a warning for self-initialised variables for any GCC version (if it's
left as-is for now, then -Winit-self can just be specified all the time for any
GCC version >= 3.4).

The situation here is slightly odd in that -Winit-self is effectively always on
for C++, so in a way it does work - it's not specifying it (or -Wno-init-self)
which doesn't!

I think it would be better to fix the documentation to reflect the current
behaviour for C++/ObjC++, and mark this bug as an enhancement request.
