[Bug fortran/43414] New: DWARF4: Use DW_AT_main_subprogram for MAIN__

[burnus at gcc dot gnu dot org]

DWARF4 draft: http://dwarfstd.org/doc/DWARF4-public-review.pdf

gfortran uses
  main()
to initialize the program and
  MAIN__
as actual Fortran program.

DWARF4 offers:
  DW_AT_main_subprogram   Main or starting subprogram
                          Unit containing main or starting subprogram

File: gcc/fortran/trans-decl.c:
The "main" program is generated in create_main_function; the "MAIN__"
subprogram is generated gfc_generate_function_code (only if
sym->attr.is_main_program).

gcc/dwarf2out.c already has DW_AT_main_subprogram defined.
