    [binutils] Handle presence of both .debug_ranges and .debug_rnglists

    With exec:
    ...
    $ g++ src/gdb/testsuite/gdb.cp/cpexprs.cc -gdwarf-5 -fdebug-types-section
    ...
    I run into:
    ...
    $ readelf -w a.out > READELF
    readelf: Error: Invalid range list entry type 126
    readelf: Error: Invalid range list entry type 60
    ...

    The executable contains both a .debug_rnglists section (for CU
    cpexprs.cc) and a .debug_ranges section (for other CUs, like crti.S).  But
    when executing display_debug_ranges for say, section .debug_rnglists it
also
    tries to use the range list references related to section .debug_ranges.

    Fix this by filtering out the .debug_range references when handling
    .debug_rnglists and vice versa.
