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.

* class.c (objc_lookup_class): Added back for compatibility with
clang which seems to emit calls to it.
