PR libstdc++/68197 fail on negative iword/pword indices
The suggested resolution of LWG 3083 is to make invalid indices
undefined, but we can fairly easily check for them and treat them as
errors in the same way as allocation failure. This avoids a segfault or
worse, setting an error flag on the stream instead.

PR libstdc++/69608 Move semantics for strstreambuf
In libstdc++ the deprecated char* streams are non-copyable, as was
required pre-C++11.
Since C++11 the standard implies that those streams should be copyable,
but doesn't specify the effects of copying them. This is surely a
defect, so for consistency with other implementations this change makes
them movable, but not copyable.

Use char_span for return type of location_get_source_line
location_get_source_line returns a const char * that isn't 0-terminated,
writing back a length through an int * param.
This is error-prone, as all call-sites have to take into account the
lack of 0-termination, and respect the length of the buffer.
It's cleaner to bundle together this pointer+length state into a class,
so this patch does so, reusing the "char_span" class that I introduced

DWARF: Add .debug_addr table header for dwarf_version >= 5.
GNU DebugFission didn't add table headers for the .debug_addr
tables, but DWARF5 does. The table header makes it possible
for a DWARF consumer to parse the address tables without having
to index all .debug_info CUs first.
We can keep using the .debug_addr section label as is, because the
DW_AT_[GNU_]addr_base attribute points at the actual address index,
which starts right after the table header. So the label is generated
at the correct location whether the header is added first or not.
Add DW_AT_addr_base instead of DW_AT_GNU_addr_base to the skeleton
CU DIE for DWARF5.

Given that the SVR4 vs PLT code model consideration is irrelevant for
this test case rather than rewriting the regular expression to match
this variant of code just enforce the PLT model by using the `-mplt'
option. It is safe to use this option unconditionally as it is silently
ignored with configurations that do not support this model, e.g. bare
metal ELF.
