[PATCH] D79895: Add a new warning to warn when passing uninitialized variables as const reference parameters to a function

> This warning can be turned off by the flag `-Wno-uninitialized-const-reference`.

Suggesting to turn off the warning should be the last resort. I am pointing to the false positives for large existing code bases from `-Wall` diagnostic.

> I don't think we can just make the diagnostic not fire for empty body consuming functions, if the function declaration and definition are in different translation units.

I am talking about the particular situation that is involves only inline functions with empty bodies. `boost::ignore_unused`-like functions are obviously come with definition.
