* Makefile.in (HOST_RTL): Add $(HOST_PREFIX)bitmap.o.

        (rtl.o, emit-rtl.o): Add dependency on bitmap.h.
        ($(HOST_PREFIX_1)rtl.o): Likewise.
        ($(HOST_PREFIX_1)bitmap.o): New host object.
        * emit-rtl.c (toplevel): Include bitmap.h.
        (gen_rtx): Handle 't' and 'b' nodes.
        * print-rtl.c (print_rtx): Handle printing NOTE_INSN_LIVE notes.
        Print block number for block begin/end notes.  Print 't' type
        nodes as a pointer.  Know that the 3rd argument of live range
        start/stop notes is really a range_info rtx.  If type is 'b', print
        out argument as a bitmap.
        * rtl.c: Include bitmap.c.
        (copy_rtx): Copy tree nodes as is.  Copy bitmaps if type is 'b'.
        (note_insn_name): Add NOTE_INSN_RANGE_{START,END}, NOTE_INSN_LIVE.
        * rtl.def (RANGE_LIVE): New node to hold live information while we
        recalculate the basic blocks.
        (RANGE_REG, RANGE_INFO): New rtl types for live range splitting.
        (RANGE_VAR): New node, to hold information saved in symbol node for New
        communicating live range information to the debug output functions.
        * rtl.h (rtunion_def): Add rttree and rtbit fields.
        (XBITMAP, XTREE): New accessor macros.
        (NOTE_LIVE_INFO): Overload NOTE_SOURCE_FILE for NOTE_INSN_LIVE notes.
        (NOTE_RANGE_INFO): Similarly for NOTE_INSN_RANGE_{START,END} notes.
        (NOTE_BLOCK_LIVE_RANGE_BLOCK): Define.
        (NOTE_INSN_RANGE_START, NOTE_INSN_RANGE_END, NOTE_INSN_LIVE): New notes.
        (RANGE_LIVE_{BITMAP,ORIG_BLOCK}): New accessor macros.
        (RANGE_REG_{SYMBOL,BLOCK}_NODE, RANGE_VAR_*): New accessor macros.
        (RANGE_INFO_*): Likewise.
        * sched.c (sched_analyze): Keep live range start/stop notes.
        (unlink_other_notes): Likewise.
        * haifa-sched.c (sched_analyze): Keep live range start/stop notes.
        (unlink_other_notes): Likewise.
        * tree.h (BLOCK_LIVE_RANGE_{START,END,VAR_FLAG}): New accessor macros.
        (BLOCK_LIVE_RANGE_FLAG): Likewise.
        (DECL_LIVE_RANGE_RTL): Likewise.
        (struct tree_block): Add live_range_flag, live_range_var_flag,
        live_range_start and live_range_end.
        (struct tree_decl): Add live_range_rtl field.
        * gengenrtl.c (type_from_format): Handle 'b' and 't'.
        (accessor_from_format): Likewise.
