Itamar 09153b8997 LibDebug: Use DW_AT_ranges to get address ranges of DIEs ...

Previously, we only supported DIEs with a contiguous address ranges and
ignored ones with a non-contiguous set of ranges.

We now check if a DIE has the DW_AT_ranges attribute, and if it does we
parse its range list.

This improves the quality of our backtraces - we previously missed many
inlined function calls because their DIEs had non-contigues address
ranges.
