PR c++/86429 - constexpr variable in lambda.

When we refer to a captured variable from a constant-expression context
inside a lambda, the closure (like any function parameter) is not constant
because we aren't in a call, so we don't have an argument.  So the capture
is non-constant.  But if the captured variable is constant, we might be able
to use it directly in constexpr evaluation.

PR libstdc++/85965 delay static assertions until types are complete

The static assertions added for PR libstdc++/48101 were at class scope
and so were evaluated too eagerly, when it might not be possible to
determine whether the function objects are invocable with the key types.
The problematic cases are where the key type is not known to be
convertible to the argument type(s) of the function object until later,
after a type has been completed. Specifically, if the key type is a
pointer to a derived class and the function object's argument type is a
pointer to a base class, then the derived-to-base conversion is only
valid once the derived type is complete.

By moving the static assertions to the destructor they will only be
evaluated when the destructor is instantiated, at which point whether
the key type can be passed to the function object should be knowable.
The ideal place to do the checks would be only when the function objects
are actually invoked, but that would mean adding the checks in numerous
places, so the destructor is used instead.

The tests need to be adjusted because the "required from here" line is
now the location of the destructor, not the point of instantiation in
the test file. For the map and multimap tests which check two
specializations, the dg-error matching the assertion text matches both
cases. Also check the diagnostic output for the template arguments, to
ensure both specializations trigger the assertion.

[PR72741] Encode OpenACC 'routine' directive's level of parallelism inside Fortran module files

If 'use'ing with an old GCC a new module file (with OpenACC 'routine'

follows:

If 'use'ing with a new GCC an old module file (without OpenACC 'routine'

PR c++/87480 - decltype of member access in default template arg

The issue here is that declval<T>().d is considered instantiation-dependent
within a template, as the access to 'd' might depend on the particular
specialization.  But when we're deducing template arguments for a call, we
know that the call and the arguments are non-dependent, so we can do the
substitution as though we aren't in a template.  Which strictly speaking we
aren't, since the default argument is considered a separate definition.

* pt.c (type_unification_real): Accept a dependent result in
template context.

S/390: Fix PR89775. Stackpointer save/restore instructions removed

Even if a global register is being clobbered in a function we usually
do not save and restore it. However, we still have to do this if it is
a special register. Most of the places in the backend handle this
correctly but not the prologue/epilogue optimization.
