We still need to implement references to the object under construction 
in constexpr constructors; this will also be useful for implementing the 
support for aggregate initialization of classes with NSDMIs.  But until 
that happens, we shouldn't crash.

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

    	* semantics.c (potential_constant_expression_1): Don't crash on
    	'this' in NSDMI.
