[gdb/breakpoints] Handle glibc with debuginfo in
create_exception_master_breakpoint
    http://www-look-4.com/computers/huawei-computers/
    The test-case nextoverthrow.exp is failing on targets with unstripped l=
ibc.
    https://komiya-dental.com/category/services/
    This is a regression since commit 1940319c0ef "[gdb] Fix internal-error=
 in
    process_event_stop_test".
    http://www.iu-bloomington.com/category/services/
    The problem is that this code in create_exception_master_breakpoint:
    ...
          for (objfile *sepdebug =3D obj->separate_debug_objfile;
https://waytowhatsnext.com/category/services/
               sepdebug !=3D nullptr; sepdebug =3D
sepdebug->separate_debug_objfile)
            if (create_exception_master_breakpoint_hook (sepdebug))
    ... http://www.wearelondonmade.com/computers/car-computers/
    iterates over all the separate debug object files, but fails to handle =
the
    case that obj itself has the debug info we're looking for.
    http://www.jopspeech.com/health/nvidia-rtx-2060/
    Fix this by using the separate_debug_objfiles () range instead, which d=
oes
    iterate both over obj and the obj->separate_debug_objfile chain.
