* Makefile.am (BFD32_LIBS): Add arange-set.lo.

  (BFD32_LIBS_CFILES): Add arange-set.c.
  (SOURCE_HFILES): Add arange-set.h
  (dwarf2.lo): Add dependency upon arange-set.h.
  (arange-set.lo): New target.
* Makefile.in: Regenerate.
* arange-set.c: New file.
* arange-set.h: New file.
* dwarf2.c: Include arange-set.h.
  (struct dwarf2_debug) Add new fields comp_unit_count and comp_unit_arange_set.
  (struct comp_unit) Replace field arange with a new field arange_set.
  (dwarf2_arange_set_allocate, dwarf2_arange_set_deallocate,
  (dwarf2_combine_arange_value, dwarf2_arange_set_new,
  (dwarf2_arange_set_with_value_new, dwarf2_comp_unit_arange_add): New
  functions to utilize arange set in dwarf2.c.
  (arange_add): Formatting change for a line longer than 80 characters.
  (decode_line_info): Replace call target arange_add with
  (dwarf2_comp_unit_arange_add.
  (read_rangelist_insert_arange_list,
  (read_rangelist_comp_unit_arange_add): New functions used as callbacks
  for read_rangelist.
  (read_rangelist): Change interface to accept a callback and data to
  allow caller to select the action peformed on a new range list read.
  (scan_unit_for_symbols): Use new interface of read_rangelist.
  (parse_comp_unit): Create an arange set for each new comp unit.  Use new
  interface of read_rangelist.  Replace call to arange_add with that to
  dwarf2_comp_unit_arange_add.
  (comp_unit_contains_address): Replace sequential search with a call to
  arange_set_lookup_address, which can handles large set efficiently.
  (stash_copy_local_aranges, stash_maybe_enable_arange_set,
  (stash_find_nearest_line_fast): New functions maintaining and using a
  valued global arange set for all compilation units to speed up
  bfd_dwarf2_find_nearest_line.
  (find_line): Use global arange set.  Replace sequential search over all
  compilation units with a call to stash_find_nearest_line_fast.  Add
  book keeping to count number of compilation units.  Replace empty
  arange list test with a call to arange_set_empty_p.
