[PATCH] D39854: [DWARFv5] Support FORM_strp in .debug_line.dwo

Use address-size zero for the DWARFDataExtractor, in the .dwo section.
This required relaxing an assertion in the line-table parser.  If there's no line-number program, the address size isn't needed, and if there is one, attempting to retrieve an address will assert farther down.

Technically we can derive the address size from the line-number program, but I wanted to leave that for the next patch.
