Log:
PR debug/24444
* config/ia64/ia64.c: Include debug.h.
(MAX_ARTIFICIAL_LABEL_BYTES): New.
(ia64_label_after_insn, ia64_dwarf2out_def_steady_cfa): New.
(IA64_CHANGE_CFA_IN_EPILOGUE): Define to 0.
(process_epilogue, process_set, process_for_unwind_directive):
Output unwind info only if requested.  Add CFA info if requested.
Add new arguments as needed.  Adjust callers.
* config/ia64/ia64.h (ARG_POINTER_CFA_OFFSET): Override
incorrect default.
(DWARF2_FRAME_INFO): Define to zero.
* config/ia64/unwind-ia64.c: Remove code that compensated for
the CFA offset error fixed above.
* config/ia64/t-ia64 (ia64.o): Depend on debug.h.
* dwarf2out.c (DWARF2_FRAME_INFO): Define default.
(dwarf2out_do_frame): Require nonzero DWARF2_UNWIND_INFO for
-funwind-tables and -fexceptions to enable frame info.
(dwarf2out_frame_init): Define initial CFA even if
DWARF2_UNWIND_INFO is disabled.  Call initial_return_save if
DWARF2_UNWIND_INFO is nonzero, not just defined.
(dwarf2out_frame_finish): Output non-EH call frame info only
if DWARF2_FRAME_INFO is nonzero.
(convert_cfa_to_loc_list,
compute_frame_pointer_to_cfa_displacement): Define even if
unwind info is not supported.
(gen_subprogram_die): Use the above unconditionally.  Remove
legacy alternate code.
* toplev.c (compile_file): Compile in call to
dwarf2out_frame_finish if DWARF2_DEBUGGING_INFO is defined.
(lang_dependent_init): Ditto for dwarf2out_frame_init.
