--- Comment #6 from Eli Friedman <efriedma at quicinc.com> ---
There's a semantic difference between the C rules and the C++ rules for
conditional operators. The result in C is always an rvalue; the result in C++
can be an lvalue.  The generated code reflects the difference in lowering for
lvalue conditional vs. rvalue conditional .

I guess we could try to reduce the number of memcpy calls we generate for
rvalue conditionals, if both operands are lvalue-ish.  But that doesn't really
seem like a priority.  So I'm just going to mark this fixed.
