[RFC] Trivialize objc-lang.c FETCH_ARGUMENT

Well, I thought I'd at least try to see if this patch would be ok. Here 
I replace the arcitecture dependant FETCH_ARGUMENT with a trivial 
implementation that does nothing. This would allow objc-lang.o to be 
linked into gdb and I commit  most or all of the remaining Objective-C 
patches. Then I could work on fixing FETCH_ARGUMENT at my leasure...

	* objc-lang.c (FETCH_ARGUMENT, CONVERT_FUNCPTR): Redefine to return
	a trivial value and remove architecture dependant compilation.
	Temporary until they get put in the gdbarch vector.
