[RFC]: Minor clean up of variable names in infrun.c

I renamed this variable to be a little more meaningful and did a little 
clean up. This is a pre-requisite for  my previous (updated) 
infrun.c/Objective-C patch.

	* infrun.c (handle_inferior_event): Rename 'tmp' to real_stop_pc.
	Remove duplicate/shadowing variable of same name.
