Fix twolf ICE for ARM

        * config/arm/arm.c (arm_emit_movpair): Handle CONST_INT.
        * config/arm/arm.md (*arm_movtas_ze): New pattern for
        movt.

You're missing an "#:upper16:" annotation in the *arm_movtas_ze pattern, c.f.
the *arm_movt pattern.

(Not posting a patch since my renewed attempt to get a copyright assignment
seems to have ended up in /dev/null over at the FSF.)
