[Bug debug/43950] New: fortran: Use DW_AT_identifier_case

["jan dot kratochvil at redhat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Fortran currently lowercases all the identifiers for DWARF.
In such case it should set DW_AT_identifier_case = DW_ID_down_case.
GDB currently assumes DW_ID_down_case for DW_LANG_Fortran* which is incorrect,
consumer should always default to DW_ID_case_sensitive according to DWARF4.

Fortran should preserve source file case
and set DW_AT_identifier_case = DW_ID_case_insensitive
GDB currently does not support it though, it is filed as:
