commit 16eb6b2db49e6cf2fdca56efd37689fcc170cd37
Author: Leszek Swirski <leszeks@google.com>

Fix dwarf2_string_attr for -gsplit-dwarf
The dwarf2_string_attr did not allow DW_FORM_GNU_str_index as a form for
string types. This manifested as null strings in the namespace_name
lookup (replaced with "(anonymous namespace)") when debugging
Fission-compiled code.
gdb/ChangeLog:
* dwarf2read.c (dwarf2_string_attr): Allow DW_FORM_GNU_strp_alt.
