re PR target/60648 (ICE (segmentation fault) in expand_binop)
PR target/60648
* expr.c (do_tablejump): Use simplify_gen_binary rather than
gen_rtx_{PLUS,MULT} to build up the address expression.
* i386/i386.c (ix86_legitimize_address): Use copy_addr_to_reg to avoid
creating non-canonical RTL.
PR target/60648
* g++.dg/pr60648.C: New test.
