ia64.c (do_spill): Pass cfa offset to move expander.

        * config/ia64/ia64.c (do_spill): Pass cfa offset to move expander.
        (do_restore): Likewise.
        (gen_movdi_x, gen_fr_spill_x, gen_fr_restore_x): New.
        (ia64_expand_prologue, ia64_expand_epilogue): Use them.
        (rtx_needs_barrier): Track actual bit manipulation for
        ar.unat moves, gr_spill, and gr_restore.
        (emit_insn_group_barriers): Special case gr_spill/gr_restore.
        (process_set): Don't handle varargs spills.
        * config/ia64/ia64.md (gr_spill): Accept cfa offset.  Emit
        .mem.offset here instead of in process_set.
        (gr_restore): Likewise.
