beam_bool: Remove a clause in initialized_regs/2 that cannot match
When scanning a reversed instruction sequence for a function, it is impossible to reach the end of the list, because each function must have a fun_info/4 instruction followed by a label/1 instruction at the beginning, and there is a clause that will handle those instructions. If for some unfathomable reason the end of the list would be reached, with this change there will be an internal compiler error and no *.beam file will be created. Thus this change is safe.
