Further conform g++'s __vmi_class_type_info to the C++ ABI specification.

2003-01-14  Jeffrey D. Oldham  <oldham@codesourcery.com>

	Further conform g++'s __vmi_class_type_info to the C++ ABI
	specification.
	* gcc/cp/rtti.c (dfs_class_hint_mark): Do not set hints not
	specified by the specification.
	(class_hint_flags): Likewise.
	* gcc/testsuite/g++.old-deja/g++.abi/vmihint.C (main): Revise
	expected flags per the specification.
	* libstdc++-v3/libsupc++/cxxabi.h
	(__vmi_class_type_info::__flags_masks): Remove enumerations not
	required by the specification.
