Previously the _M_Nb member was incremented before calling
_M_unchecked_set which meant that the bit being set was out of bounds.
It either set the wrong bit in an allocated word, or accessed beyond the
end of the allocated memory in the _M_w vector. The fix for the bug is
to update the _M_Nb member after using it as an index.
As an optimisation, when a new block needs to be appended the call to
_M_unchecked_set can be avoided by appending a block with the least
significant bit already set to the desired value.

PR bootstrap/87747 would have been significantly easier to track down if
the pool allocator had faulted an attempt to configure it to allocate
zero-sized objects. Instead, this slipped through and we later hit
memory corruption when the assumed size turned out to be different to
the configured size.
While, theoretically, there might be a use case for this, it seems
unlikely to me that GCC would have such a use. So this patch adds a
checking assert that the object size is not zero.

PR c++/87721 reports a crash in get_substring_ranges_for_loc introduced
by r265271, my fix for PR 87562.
The new issue occurs when attempting to get a location with a string
literal inside a macro in which the first token is __FILE__ (formed via
concatenation). Attempting to get the spelling location of __FILE__
fails, leading to NULL for start_ord_map and final_ord_map, and thus
a NULL pointer dereference.
Given that our "on-demand" substring locations approach reparses the
string literals, there isn't a good way to access the locations inside
such string literals: attempting to reparse __FILE__ fails with a
"missing open quote".
This patch applies the easy fix by gracefully rejecting the case where
the spelling locations for the start or finish give us NULL maps.

In the C++ FE, after emitting various errors about unrecognized names,
the parser can call
suggest_alternatives_for
and/or
suggest_alternative_in_explicit_scope.
These can issue zero or more suggestions for the unrecognized name,
or various other "note" diagnostics suggesting how to fix the problem.
For example, currently g++ emits:
t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
t.cc:12:3: note: suggested alternative: 'gtk_widget_show_all'
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
| gtk_widget_show_all
This patch consolidates the common case when there is a single
candidate, so that the error can issue a fix-it hint directly.
This simplifies the above to:
t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope;
did you mean 'gtk_widget_show_all'?
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
| gtk_widget_show_all
omitting the second "note" diagnostic.
Doing so requires changing the above "suggest_" functions so that
rather than being called after "error" and emitting a note directly,
they are called before the "error", and return a name_hint, which
can contain a suggestion and/or a deferred diagnostic. The "single
candidate" case is handled via a suggestion, and the "multiple
candidates" case via a new subclass of deferred_diagnostic.
There was some complication due to the fact that we don't always have
enough location information to issue a fix-it hint. Specifically,
for the case in qualified_name_lookup_error, the location is that of
the name, but the location of the qualifier prefix isn't reliably
available. For some hints, e.g. spell-corrections, the replacement
is of the name, and for others, e.g. parent namespaces, it's for the
qualified name. The patch addresses this by splitting this case out
into a new "suggest_alternatives_in_other_namespaces" function, for
which fix-it hints aren't issued.
Another complication is that of emitting a note when
--param cxx-max-namespaces-for-diagnostic-help
is reached. The patch emulates the existing behavior by emitting
the note from a deferred_diagnostic. This potentially needs to
co-exist with another deferred_diagnostic, so it works as a decorator
around any other such deferred_diagnostic. Doing so requires slightly
extending class name_hint.
On adding test coverage for the various cases, I discovered that
after emitting a "FOO is not a namespace-name" error, we also emit
a "expected namespace-name before" error. The patch removes this
second error for the case where it's redundant, simplifying this case
from e.g.:
spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name
10 | using namespace outer::inner_ms;
| ^~~~~~~~
spellcheck-ns.C:10:24: note: suggested alternative: 'inner_ns'
10 | using namespace outer::inner_ms;
| ^~~~~~~~
| inner_ns
spellcheck-ns.C:10:32: error: expected namespace-name before ';' token
10 | using namespace outer::inner_ms;
| ^
to:
spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name;
did you mean 'inner_ns'?
10 | using namespace outer::inner_ms;
| ^~~~~~~~
| inner_ns

This patch eliminates the arglocs array I introduced to build_over_call
in r264887, and eliminates the call to maybe_constant_value when building
"fargs" (thus retaining location wrapper nodes).
Instead, this patch requires that any checks within
check_function_arguments that need folded arguments do their own folding.
Of the various checks:
(a) check_function_nonnull already calls fold_for_warn,
(b) check_function_format doesn't need folding
(c) check_function_sentinel needs fold_for_warn in one place, which the
patch adds, and
(d) check_function_restrict needs per-argument folding, which the patch
adds. Given that it scans before and after resetting TREE_VISITED on
each argument, it seemed best to make a copy of the array, folding each
argument from the outset, rather than repeatedly calling fold_for_warn;

Due to the changes in PR81878 builds of GCC8 and trunk are impossible
with Ada enabled[1][2].
The reason the patch breaks the bootstrap is due to how gnatlink receives it's
arguments.
gnatlink is usually invoked as
$(GNATLINK) -v gnatcmd -o ../../gnat$(exeext) \
--GCC="$(CC) $(ADA_INCLUDES)" --LINK="$(GCC_LINK)" $(TOOLS_LIBS)
so it passes $(CC) and $(GCC_LINK) as quoted arguments to the program.
Because of this quotation the msys2 shell does not translate any paths in
$(CC) and $(GCC_LINK) from their Unix version to their Windows version.
Furthermore because there are multiple paths in the values separated by space
and because the paths often contain a prefix like -L (e.g. -L/f/foo) we can't
use `fix_srcfile_path` to fix this.
An alternative solution would have been to create a stub program that echos the
commandline options it receives back, and calling this program with $(CC) and $(GCC_LINK)
unquoted to get them translated. However this was a bit more invasive.
So instead for native compilations we add -B../../ such that it picks up the lto plugin
from the previous built compiler. Since it's native there shouldn't be a mismatch here.
