Correct decls for functions which do not pass actual arguments.
A wrong decl for findloc caused segfaults at runtime on
Darwin for ARM; however, this is only a symptom of a larger
disease: The declarations for our library functions are often
inconsistent. This patch solves that problem for the functions
specifically for the functions for which we do not pass optional
arguments, i.e. findloc and (min|max)loc.
It works by saving the symbols of the specific functions in
gfc_intrinsic_namespace and by generating the formal argument
lists from the actual argument lists. Because symbols are
re-used, so are the backend decls.

c++: Fix verify_ctor_sanity ICE [PR96241]
The code added in r10-6437 caused us to create a CONSTRUCTOR when we're
{}-initializing an aggregate. Then we pass this new CONSTRUCTOR down to
cxx_eval_constant_expression which, if the CONSTRUCTOR isn't TREE_CONSTANT
or reduced_constant_expression_p, calls cxx_eval_bare_aggregate. In
this case the CONSTRUCTOR wasn't reduced_constant_expression_p because
for r_c_e_p a CONST_DECL isn't good enough so it returns false. So we
go to cxx_eval_bare_aggregate where we crash, because ctx->ctor wasn't
set up properly. So my fix is to do so. Since we're value-initializing,
I'm not setting CONSTRUCTOR_NO_CLEARING. To avoid keeping a garbage
constructor around, I call free_constructor in case the evaluation did
not use it.

fwprop creates the invalid address due to rs6000_legitimate_address_p

c, c++: Implement -Wsizeof-array-div [PR91741]
This patch implements a new warning, -Wsizeof-array-div. It warns about
code like
int arr[10];
sizeof (arr) / sizeof (short);
where we have a division of two sizeof expressions, where the first
argument is an array, and the second sizeof does not equal the size
of the array element. See e.g. <https://www.viva64.com/en/examples/v706/>.
Clang makes it possible to suppress the warning by parenthesizing the
second sizeof like this:
sizeof (arr) / (sizeof (short));
so I followed suit. In the C++ FE this was rather easy, because
finish_parenthesized_expr already set TREE_NO_WARNING. In the C FE
I've added a new tree code, PAREN_SIZEOF_EXPR, to discern between the
non-() and () versions.
This warning is enabled by -Wall. An example of the output:
x.c:5:23: warning: expression does not compute the number of elements in this array; element type is ‘int’, not ‘short int’ [-Wsizeof-array-div]
5 | return sizeof (arr) / sizeof (short);

testsuite: Add noexcept(false) to throwing destructor
I think this test is intended to check this property of the C++
standard:
"If a destructor directly invoked by stack unwinding exits via an
exception, std::terminate is invoked." [except.throw]
Since C++11 any exception escaping a destructor will call
std::terminate, so the test would terminate even if the unwinding
behaviour was wrong.
Give the destructor a potentially-throwing exception specification,
so that we know that terminate was called for the right reason.

Jeff has noticed and I've confirmed that config/i386/i386.h header which is
installed on x86 in plugin/include/ directory newly in GCC 11 has
which breaks all plugins that include tm.h etc. because that header is not
shipped.
The following patch seems to fix that. Unfortunately it isn't just a matter
of TM_H += t-i386 change, because the header has full path and therefore
needs to be installed in its full path.
Additionally, I've noticed that the b-header-vars generation is completely
broken, it will just throw many of the dependencies away, because it
incorrectly removed everything from first ... remaining till the last /,
while what it clearly wants to do is remove each ... till last / in the same
header path (i.e. instead of .* should have used [^ ]* and g modifier).
I've also noticed that some other headers mentioned in #include of other
headers aren't included (gomp-constants.h as dependency of omp-general.h
and various dependencies of expr.h (where omp-general.h and expr.h were
previously installed)).

stor-layout: Reject forming arrays with elt sizes not divisible by elt alignment [PR97164]
As mentioned in the PR, since 2005 we reject if array elements are smaller
than their alignment (i.e. overaligned elements), because such arrays don't
make much sense, only their first element is guaranteed to be aligned as
user requested, but the next element can't be.
The following testcases show something we've been silent about but is
equally bad, the 2005 case is just the most common special case of that
the array element size is not divisible by the alignment. In those arrays
too only the first element is guaranteed to be properly aligned and the
second one can't be.
This patch rejects those cases too, but keeps the existing wording for the
old common case.
Unfortunately, the patch breaks bootstrap, because libbid uses this mess
(forms arrays with 24 byte long elements with 16 byte element alignment).
I don't really see justification for that, so I've decreased the alignment
to 8 bytes instead.

libstdc++: Reduce header dependencies in and on <memory>
By moving std::make_obj_using_allocator and the related "utility
functions for uses-allocator construction" to a new header, we can avoid
including the whole of <memory> in <scoped_allocator> and
<memory_resource>.
In order to simplify the implementation of those utility functions they
now use concepts unconditionally. They are no longer defined if
__cpp_concepts is not defined. To simplify the code that uses those
functions I've introduced a __cpp_lib_make_obj_using_allocator feature
test macro (not specified in the standard, which might be an oversight).
That allows the code in <memory_resource> and <scoped_allocator> to
check the feature test macro to decide whether to use the new utilities,
or fall back to the C++17 code.
At the same time, this reshuffles some of the headers included by
<memory> so that they are (mostly?) self-contained. It should no longer
be necessary to include other headers before <bits/shared_ptr.h> when
other parts of the library want to use std::shared_ptr without including
the whole of <memory>.
