PR rtl-optimization/50249
	* reload1.c (reload_reg_reaches_end_p): Accept a reloadnum argument
	instead of opnum and type.  All callers changed.  Remove useless
	declaration.
	Search forward for other reloads of the same type for the same operand
	using the same register; if any are found, return false.
	(reload_regs_reach_end_p): Same argument changes; all callers changed.
