gnuv3_rtti_type still gets confused sometimes, by constructor vtables and
namespaces at least.  This wouldn't be a big problem, as mostly I don't
care what the real type is, except that it gives an error and aborts.  If
I'm just trying to print the contents of a pointer, this is rather
annoying.

This patch changes the errors to warnings, so that I get the normal output
which is all I really care about.

OK?

	* gnu-v3-abi.c (gnuv3_rtti_type): If we get confused, just warn
	and return NULL.
