[ARM] Simplify logical DImode iterators
Further simplify the logical DImode expander using code iterator and
obtab attributes. This avoids adding unnecessary code_attr entries.
gcc/
* config/arm/arm.md (<logical_op>di3): Use <optab> and <CODE>.
* config/arm/iterators.md (optab): Add and, ior, xor entries.
(logical_op): Remove code attribute.
(logical_OP): Likewise.
