gcc     * config/arm/arm.c (arm_option_override_internal): Disable
        interworking if the target does not support thumb instructions.
        (arm_reload_in_hi): Handle the case where a register to register
        move needs reloading because there is no simple pattern to handle
        it.
        (arm_reload_out_hi): Likewise.

tests   * gcc.target/arm/pr62554.c: New test.
        * gcc.target/arm/pr69610-1.c: New test.
        * gcc.target/arm/pr69610-2.c: New test.
