In change reports for function sub-type changes, for the C language,
when the name of the function is different from its linkage name, even
when the function symbol has no aliases, show the symbol information
of the function.
* include/abg-ir.h (translation_unit::language): New enum type.
(translation_unit::{get_language, set_language}): Declare new
accessors.
(translation_unit_language_to_string)
(string_to_translation_unit_language, is_c_language)
(is_cplus_plus_language): Declare new functions.
* src/abg-ir.cc (translation_unit::priv::language_): New data
member.
(translation_unit::priv::language_): Initialize it.
(translation_unit::{set_language, get_language}): Define new
member functions.
(translation_unit_language_to_string)
(string_to_translation_unit_language, is_c_language)
(is_cplus_plus_language): Define new functions.
* src/abg-dwarf-reader.cc (dwarf_language_to_tu_language): New
static function.
(build_translation_unit_and_add_to_ir): Read the language of the
translation unit.
* src/abg-comparison.cc (corpus_diff::report): When reporting a
change in a function sub-type, if we are in C language translation
unit, if the function name is different from its linkage name,
even if the symbol doesn't have any alias, show symbol
information.
* src/abg-reader.cc (read_translation_unit_from_input): Read the
'language' property of the translation unit, if present.
* src/abg-writer.cc (write_translation_unit): Write the 'language'
property to the translation unit, if present.
* tests/data/test-read-dwarf/test0.abi: Adjust for the new
'language' property of the 'abi-instr' element.
* tests/data/test-read-dwarf/test1.abi: Likewise.
* tests/data/test-read-dwarf/test2.so.abi: Likewise.
* tests/data/test-read-dwarf/test3.so.abi: Likewise.
* tests/data/test-read-dwarf/test4.so.abi: Likewise.
* tests/data/test-read-dwarf/test5.o.abi: Likewise.
* tests/data/test-read-dwarf/test6.so.abi: Likewise.
* tests/data/test-read-dwarf/test7.so.abi: Likewise.
