PR 17531
* expr.c (expand_expr_addr_expr_1): Only assemble_external for decls.
Don't check VOIDmode here. Force PLUS operands to common type.
(expand_expr_addr_expr): Do VOIDmode check earlier. Force use of
Pmode if given a non pointer type.
PR 17531
* optabs.c (expand_binop): Force constants to the correct mode.
