[PATCH v2 2/4] DWARF 5 support: Handle DW_FORM_strx
* Handle DW_FORM_strx forms everywhere. Tested with CC=/usr/bin/gcc (version 8.3.0) against master branch (also with -gsplit-dwarf and -gdwarf-4 flags) and there was no increase in the set of tests that fails. This is part of an effort to support DWARF 5 in gdb. gdb/ChangeLog: * dwarf2read.c (skip_one_die): Handle DW_FORM_strx forms. (dwarf2_string_attr): Likewise.
