C++ PATCH for c++/81067, redundant NULL warning

Subject: C++ PATCH for c++/81067, redundant NULL warning
Authentication-results: sourceware.org; auth=none

My June 9 patch to remove the call to scalar_constant_value from
convert_like_real wrongly also removed the NULL handling that avoids
repeated warnings.  This patch restores that code.

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