        * config/alpha/alpha.c (get_unaligned_address): Remove extra_offset
        argument; update all callers.
        (get_unaligned_offset): New.
        * config/alpha/alpha.md (extendqidi2, extendhidi2): Don't use
        get_unaligned_address, just pass on the address directly.
        (unaligned_extendqidi): Use gen_lowpart instead of open-coding
        the subreg in the helper patterns.
        (unaligned_extendqidi_le): Use get_unaligned_offset.
        (unaligned_extendqidi_be, unaligned_extendhidi_le): Likewise.
        (unaligned_extendhidi_be): Likewise.
        (unaligned_extendhidi): Tidy.
