[Bug debug/32563] [4.2/4.3 regression] ICE on pointer arithmetic

With - 1, we get:
(plus:DI (symbol_ref:DI ("a") [flags 0x1402] <var_decl 0x42510ba0 a>)
    (const_int -1 [0xffffffffffffffff]))

While with +1, we get:
(const:SI (plus:SI (symbol_ref:SI ("a") [flags 0x1402] <var_decl 0x42510b40 a>)
        (const_int 1 [0x1])))

Notice the wrapper of const.
