Change direct references to the isa pointer to calls to object_getClass(). In

Browse source 
discussion with Steve Naroff (before he left Apple) it was decided that the isa
pointer should be regarded as an implementation detail and not part of the
language, so direct references to it are deprecated (on OS X).  This gives the
runtime a bit more freedom to do secret isa-swizzling tricks.

I've had these changes sitting in my copy for ages - no idea why they weren't
committed.
