[PATCH 168/236] final_start_function takes an rtx_insn

[David Malcolm <dmalcolm at redhat dot com>]

All in-tree users of final_start_function now pass an rtx_insn * as the
first param.

gcc/
	* output.h (final_start_function): Strengthen param 1 from rtx to
	rtx_insn *.

	* final.c (final_start_function): Likewise, renaming back from
	"uncast_first" to "first", and dropping the checked cast from rtx
	to rtx_insn *.
