And a further update that handles direct-initialization, which the
actual proposal doesn't specify at all.  I'm dealing with
direct-initialization from a type with a conversion operator that
produces a prvalue of the type being initialized by treating
direct-initialization from an unrelated type like copy-initialization
with access to explicit conversions.  And relatedly, for conversion
from a braced-init-list with a single element: we look for
constructors as normal, but also consider conversion functions from
the element type.  I should probably write up some wording for this
for Issaquah.

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