re PR debug/48253 (Further .debug_aranges issues)

PR debug/48253
* dwarf2out.c (struct dw_fde_struct): Remove dw_fde_hot_section_label,
dw_fde_hot_section_end_label, dw_fde_unlikely_section_label,
dw_fde_unlikely_section_end_label, cold_in_std_section,
dw_fde_switched_sections and dw_fde_switched_cold_to_hot fields.
Add dw_fde_second_begin, dw_fde_second_end and second_in_std_section
fields.
(output_fde): Use dw_fde_second_{begin,end} if second is
true, otherwise dw_fde_{begin,end}.
(output_call_frame_info): Test dw_fde_second_begin != NULL
instead of dw_fde_switched_sections.
(dwarf2out_begin_prologue): Stop initializing removed dw_fde_struct
fields, initialize new fields.  Initialize in_std_section
unconditionally from the first partition.
(dwarf2out_end_epilogue): Don't override dw_fde_end when
dw_fde_second_begin is non-NULL.
(dwarf2out_switch_text_section): Stop initializing removed
dw_fde_struct fields, initialize new fields, initialize
also dw_fde_end here.  Set dw_fde_switch_cfi even when
dwarf2out_do_cfi_asm ().  Call var_location_switch_text_section.
(struct var_loc_list_def): Add last_before_switch field.
(arange_table, arange_table_allocated, arange_table_in_use,
ARANGE_TABLE_INCREMENT, add_arange): Removed.
(size_of_aranges): Count !in_std_section and !second_in_std_section
hunks in fdes, instead of looking at arange_table_in_use.
(output_aranges): Add aranges_length argument, don't call
size_of_aranges here.  Instead of using aranges_table*
emit ranges for fdes when !in_std_section resp.
!second_in_std_section.
(dw_loc_list): Break ranges crossing section switch.
(convert_cfa_to_fb_loc_list): Likewise.  If switched sections,
use dw_fde_second_end instead of dw_fde_end as end of last
range.
(gen_subprogram_die): Don't call add_arange.  Use
dw_fde_{begin,end} for first partition and if switched
section dw_fde_second_{begin,end} for the second.
(var_location_switch_text_section_1,
var_location_switch_text_section): New functions.
(dwarf2out_begin_function): Initialize cold_text_section even
when function_section () isn't text_section.
(prune_unused_types): Don't walk arange_table.
(dwarf2out_finish): Don't needlessly test
flag_reorder_blocks_and_partition when testing cold_text_section_used.
If info_section_emitted, call size_of_aranges and if it indicates
non-empty .debug_aranges, call output_aranges with the computed
size.  Stop using removed dw_fde_struct fields, use
dw_fde_{begin,end} for first partition and dw_fde_second_{begin,end}
for second.
