Disable the l-value to r-value conversion on C++ class types passed
to varargs functions in unevaluated contexts.  AFAICT, there is no
standards justification for this, but it matches what other compilers do
and therefore preserves compatibility with certain template metaprogramming
idioms.

Should fix self-host.
