In both verbose and non-verbose mode we will now use the
`llvm::dwarf::LanguageDescription` to turn the version into a human
readable string. In verbose mode we also display the raw version code
(similar to how we display addresses in verbose mode). To make the
version code and prettified easier to distinguish, we print the
prettified name in colour (if available), which is consistent with how
`DW_AT_language` is printed in colour.
Before:
```
0x0000000c: DW_TAG_compile_unit
DW_AT_language_name (DW_LNAME_C)
DW_AT_language_version (201112)
```
After:
```
0x0000000c: DW_TAG_compile_unit
DW_AT_language_name (DW_LNAME_C)
DW_AT_language_version (201112 C11)
```
