[arm] Rewrite addsi3_carryin_shift_<optab> in canonical form

The add-with-carry operation which involves a shift doesn't match at present
because it isn't matching the canonical form generated by combine.  Fixing
this is simply a matter of re-ordering the operands.

* config/arm/arm.md (addsi3_carryin_shift_<optab>): Reorder operands
to match canonical form.
