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;
   |                        ^~~~~~~~

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.
