llvm-dwarfdump: Add support for dumping the .debug_loc section

Browse Source 
This is a basic implementation - we still don't have any support (that I
know of) for dumping DWARF expressions in a meaningful way, so the
location information itself is just printed as a sequence of bytes as we
do elsewhere.
