Wmissing-base-class-initializer (PR7651 Define -Wextra strictly in terms of other warning flags)

["Manuel LÃpez-IbÃÃez" <lopezibanez at gmail dot com>]

:ADDPATCH C++:

This patch continues the effort to fix PR7651 [1].

A new option -Wmissing-base-class-initializer takes over the warning
for a base class that is not initialized in a derived class' copy
constructor. The new
option is enabled by -Wextra, so we keep the current behaviour but add
the ability to enable/disable this individual warning.

Bootstrapped and regression tested with --enable-languages=all on
i686-pc-linux-gnu.

OK for mainline?
