Add parsing for several new attribute classes. 

- Collectively the previous set of changes get us minimally parsing
some of the new DWARF4 output from gcc 4.7 as well as some of the
draft DWARF5 extensions, which allows us to handle such executables
a bit more gracefully. Not all of the new information is made use of
as yet though. Should resolve #9799.
