[Bug fortran/11560] New: Support case-preserving case-insensitive identifier

[jan dot kratochvil at redhat dot com]

Currently gfortran and even iFort (Intel Fortran) lowercase all the identifiers.
GDB uses:
    case_sensitivity = current_language->la_case_sensitivity;
const struct language_defn f_language_defn =
  case_sensitive_off,
and in such case lowercases the string in lookup_symbol_in_language.

While iFort lowercases identifiers it explicitly uppercases the module names:
l_cprof_p_11.1.072_intel64.tgz
    <66>   DW_AT_producer    : Intel(R) Fortran Compiler Fixes RangesRelative
 <1><234>: Abbrev Number: 6 (DW_TAG_module)
    <238>   DW_AT_name        : MODMANY

This way module-fully-qualified-name "`modmany`symbol" can never be looked up on
iFort produced inferior (this module support is still not in FSF GDB HEAD).

DWARF3 supports: DW_AT_identifier_case with DW_ID_case_insensitive (+others)
None of GDB, gfortran or iFort support it.

Proper DW_AT_identifier_case would enable gfortran to preserve source file
identifiers case.

Could you file a gfortran bug report?
