split up some variables to use rtx_insn * more 

gcc/ChangeLog:

2016-11-01  Trevor Saunders  <tbsaunde+gcc@tbsaunde.org>

	* config/alpha/alpha.c (alpha_legitimize_address_1): Split up
	variables so some can be rtx_insn *.
	(alpha_emit_xfloating_libcall): Likewise.
	* config/mips/mips.c (mips_call_tls_get_addr): Likewise.
	(mips_legitimize_tls_address): Likewise.
	* optabs.c (expand_binop): Likewise.
	* reload1.c (gen_reload): Likewise.
