My patch to exclude assignments in the actual initializer from being
considered constant-expressions broke this case, where we represent a
trivial copy constructor with a MODIFY_EXPR.  Fixed by indicating that
we are effectively in a call to a constexpr function.

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