PR libstdc++/87822 fix layout change for nested std::pair

The introduction of the empty __pair_base base class for PR 86751
changed the layout of std::pair<std::pair<...>, ...>. The outer pair and
its first member both have a base class of the same type, which cannot
exist at the same address. This causes the first member to be at a
non-zero offset.

The solution is to make the base class depend on the template
parameters, so that each pair type has a different base class type,
which allows the base classes of the outer pair and its first member to
have the same address.

option when in PIC mode as per documentation rather than always check
for target_word_relocation together with flag_pic.

PR libstdc++/87784 fix dynamic_bitset::push_back

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.

Don't allow the pool allocator to be configured to allocate zero-sized objects

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

Fix ICE in get_substring_ranges_for_loc on __FILE__ (PR c++/87721)

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.

C++: simplify output from suggest_alternatives_for

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:10:32: 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'?

Folding and check_function_arguments

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;

[rs6000] Consistently use '__vector' instead of 'vector'

Revision r265535 committed changes that used 'vector' instead of the
preferred '__vector'.  There is a reason that '__vector' is preferred,
because it ensures no conflicts with C++ namespace.  Indeed,
gcc/config/rs6000/xmmintrin.h undefines it, leading to errors:

  gcc/include/xmmintrin.h:999:20: error: 'vector' undeclared (first use in this function); did you mean 'vec_or'?
  gcc/include/xmmintrin.h:999:20: note: each undeclared identifier is reported only once for each function it appears in
  gcc/include/xmmintrin.h:999:26: error: expected ')' before 'long'
  gcc/include/xmmintrin.h:999:37: error: expected ')' before 'result'

Also fixed a few whitespace issues.

Fix mingw-w64 Ada native bootstrap (PR81878).

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.
