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. From-SVN: r241770
