ix86_expand_call: convert return type to rtx_insn *

Browse source 
Eliminate an "as_a <rtx_insn *>()" cast.

gcc/ChangeLog:
	* config/i386/i386-protos.h (ix86_expand_call): Strengthen return
	type from "rtx" to "rtx_insn *".
	* config/i386/i386.c (ix86_expand_split_stack_prologue): Likewise
	for local "call_insn", removing cast.
	(ix86_expand_call): Likewise, introducing a "call_insn" local.
