    PR27202, readelf -wL doesn't work on ".loc 0"

    For DWARF revision 4 and earlier, display_debug_lines_decoded
    populates the file_table array with entries read from .debug_line
    after the directory table.  file_table[0] contains the first entry.
    DWARF rev 4 line number programs index this entry as file number one.
    DWARF revision 5 changes .debug_line format quite extensively, and in
    particular gives file number zero a meaning.

            PR 27202
            * dwarf.c (display_debug_lines_decoded): Correct indexing used
            for DWARF5 files.
