This pull request adds support for parsing the source language in both DWARF and CodeView. Specifically, - The `LVSourceLanguage` class is introduced to represent any supported language by any of the debug info representations. - Update `LVDWARFReader.cpp` and `LVCodeViewVisitor.cpp` to parse the source language where it applies. Added a new `=Language` attribute; `getAttributeLanguage()` is internally used to control whether this information is being printed.

|

; 'InlineFuction'.
|
|
; The DWARF generated by GCC/Clang show those variables at the correct
|
|
; lexical scope: '3' and '4' respectively.
