PR debug/38757 gcc does not emit DW_LANG_C99.
For C and C++ add the language standard version in use to lang_hooks.name.
Change users of lang_hook.name to check with new functions lang_GNU_C or
lang_GNU_CXX. In dwarf2out.c output the DW_LANG_C version from the
lang_hooks.name and merge any LTO TRANSLATION_UNIT_LANGUAGE found. Adds
two testcases to dwarf2.exp to check the right DWARF DW_AT_language is set
on the compile_unit depending on the -std=c89 or -std=c99 setting.
