Implement support for call site extensions

gcc 4.7 implements some new draft extensions to DWARF with respect to call site information, as documented at http://www.dwarfstd.org/ShowIssue.php?issue=100909.2&type=open
These need to be eventually properly handled, but at least the minimum needs to be implemented to parse them at first so we can properly handle binaries with those extensions.
