C++ Patch for PR c++/48859

[Fabien Chêne]

Hello,

Here the problem is that we were recursing even if there was a user
defined constructor. In fact, the check was only done at the top, not
in nested fields.
If there is a user defined constructor, uninitialized const or
reference members are diagnosed elsewhere.
Bootstraped and tested on x86_64-unknown-linux-gnu.

OK for trunk and 4.6 ?
