Changed calls to 'fastClass()' to use 'GSObjCClassOfObject()' and
added that to NSObjCRuntime.h. Removed central class and
implementation caching from NSObject.m and fast.x since it was not
being effectively used. New intention to do removal of fast.x and
add similar functionality to NSObjCRuntime.h - intention being to
combine functionality of fast access to the runtime, and hiding both
GNU and Apple runtime behind a single interface.

* This file is all to do with improving performance by avoiding the
* Objective-C messaging overhead in time-critical code.
*
* The motiviation behind it is to keep all the information needed to
* do that in one place (using a single mechanism), so that optimization
* attempts can be kept track of.
* THIS STUFF IS GOING AWAY!
*
* The optimisations are of three sorts -
*
* 1. inline functions
* There are many operations that can be speeded up by using inline
* code to examine objects rather than sending messages to them to
* ask them about themselves. Often, the objc runtime provides
* functions to do this, but these sometimes perform unnecessary
* checks. Here we attempt to provide some basics.
*
* 2. class comparison
* It is often necessary to check the class of objects - instead of
* using [+class] method, we can cache certain classes in a global
* structure (The [NSObject +initialize] method does the caching)
* and refer to the structure elements directly.
*
* 3. direct method despatch
* A common techique is to obtain the method implementation for a
* specific message sent to a particular class of object, and call
* the implementation directly to avoid repeated lookup within the
* objc runtime.
* While there is no huge speed advantage to caching the method
* implementations, it does make it easy to search the source for
* code that is using this technique and referring to a cached
* method implementation.
* The intention is to provide similar functionality in NSObjCRuntime.h
* There will be GNUstep specific (mostly inline) functions added to
* the header to provide direct access to runtime functinality and the
* internals of objects. Hopefully a simple configuration option will
* let us build for either the GNU or the Apple runtime.
