[llvm-dwarfdump] - Add the support of parsing .debug_loclists. This teaches llvm-dwarfdump to dump the content of .debug_loclists sections. It converts the DWARFDebugLocDWO class to DWARFDebugLoclists, teaches llvm-dwarfdump about .debug_loclists section and adds the implementation for parsing the DW_LLE_offset_pair entries.

# CHECK-NEXT: 0x0000000c:
DWARFDebugLoclists: stricter base address handling Summary: This removes the use of zero as a base address in section-based dumping. Although this will often be true for (unlinked) object files with a single compile unit, it is not true in general. This means that section-based dumping will not be able to resolve entries referencing the base address (DW_LLE_offset_pair) -- it wasn't able to do that correctly before either, but now it will be more explicit about it. One exception to that is if the location list contains an explicit DW_LLE_base_address entry -- in this case the dumper will pick it up, and resolve subsequent entries normally. The patch also removes the fallback to zero in the "inline" dumping in case the compile unit does not contain a base address.

# CHECK-NEXT: DW_LLE_offset_pair (0x0000000000000000, 0x0000000000000010): DW_OP_breg5 RDI+0
DWARFDebugLoclists: Move to a incremental parsing model Summary: This patch stems from the discussion D68270 (including some offline talks). The idea is to provide an "incremental" api for parsing location lists, which will avoid caching or materializing parsed data. An additional goal is to provide a high level location list api, which abstracts the differences between different encoding schemes, and can be used by users which don't care about those (such as LLDB). This patch implements the first part. It implements a call-back based "visitLocationList" api. This function parses a single location list, calling a user-specified callback for each entry. This is going to be the base api, which other location list functions (right now, just the dumping code) are going to be based on. Future patches will do something similar for the v4 location lists, and add a mechanism to translate raw entries into concrete address ranges.
