C++ PATCHes for core 1358, 1360, c++/50248 (constexpr, templates, default constructor)

A followup: non-literal argument types shouldn't change the constexpr 
flag either, and we shouldn't crash when a constructor initializes bases 
as well as members (50296).  I'm not sure how my testing missed that bug...

Tested x86_64-pc-linux-gnu, applying to trunk.

I fail to see what the patch below has to do with the cover letter you
wrote above.  Am I missing something?
