[PATCH c++/57709] Wshadow is too strict / has false positives

[Manuel López-Ibáñez <lopezibanez at gmail dot com>]

In GCC 4.8 I implemented:

"The option -Wshadow no longer warns if a declaration shadows a
function declaration, unless the former declares a function or pointer
to function, because this is a common and valid case in real-world
code."

This patch applies the same heuristic to member functions.

Bootstrapped and regression tested on x86_64-linux-gnu.

OK?
