	* emit-rtl.c (unshare_all_rtl_1): New name of unshare_all_rtl.
	(unshare_all_rtl_again): Call unshare_all_rtl_1.
	(unshare_all_rtl): New.
	* function.c (instantiate_virtual_regs): Remove parameters.
	* function.h (instantiate_virtual_regs): Add prototype.
	* rtl.h (unshare_all_rtl): Add prototype.
	* tree.h (instantiate_virtual_regs, unshare_all_rtl): Remove
	prototype.
	* passes.c: Remove assertions on the parameters to
	rest_of_handle_* functions.  Remove the parameters to
	the functions, replacing decl with current_function_decl
	and insns with get_insns ().
