rs6000.c (rs6000_output_function_epilogue): Use a name for the tbtab label that depends on the function asm name.

	* config/rs6000/rs6000.c (rs6000_output_function_epilogue): Use a
	name for the tbtab label that depends on the function asm name.
	Don't output tbtab label unless optional_tbtab.
	(output_mi_thunk): Formatting.
