The `llvm-gcc` front-end has been EOL'd at least since 2011 (based on some `git` archeology). And Clang/LLVM has been removing references to it ever since. This patch removes the remaining references to it from LLDB. One benefit of this is that it will allow us to remove the code checking for `DW_AT_decl_file_attributes_are_invalid` and `Supports_DW_AT_APPLE_objc_complete_type`.
