	PR libobjc/49883
	* init.c (__objc_exec_class): Work around a bug in clang's code
	generation.  Clang sets the class->info field to values different
	from 0x1 or 0x2 (the only allowed values in the traditional GNU
	Objective-C runtime ABI) to store some additional information, but
	this breaks backwards compatibility.  Wipe out all the bits in the
	fields other than the first two upon loading a class.
