C++ PATCH for c++/60980 (value-initialization of array member)

[Jason Merrill]

[-- Attachment #1: Type: text/plain, Size: 216 bytes --]

My change to handle trivial but not callable constructors mistakenly 
removed the check that an object is of class type before we try to call 
its constructor.

Tested x86_64-pc-linux-gnu, applying to trunk and 4.9.
