Without this, after r15-6415-g586477d67bf2e3, you'll see,
for targets where int32_t is a typedef of long int (beware
of artificially broken lines):

Getting coarray data from remote images was slow, inefficient and did
not work for object files that where not compiled with coarray support
for derived types with allocatable/pointer components.  The old approach
emulated accessing data through a whole structure ref, which was error
prone for corner cases.  Furthermore was did it have a runtime
complexity of O(N), where N is the number of allocatable/pointer
components and descriptors involved.  Each of those needed communication
twice.  The new approach creates a routine for each access into a
coarray object putting all required operations there.  Looking a
tree-dump one will see those small routines.  But this time it is just
compiled fortran with all the knowledge of the compiler of bounds and so
on.  New paradigms will be available out of the box.  Furthermore is the
complexity of the communication reduced to be O(1).  E.g. the mpi
implementation sends one message for the parameters of the access and
one message back with the results without caring about the number of
allocatable/pointer/descriptor components in the access.

Identification of access routines is done be adding them to a hash map,
where the hash is the same on all images.  Translating the hash to an
index, which is the same on all images again, allows for fast calls of
the access routines.  Resolving the hash to an index is cached at
runtime, preventing additional hash map lookups.  A hashmap was use
because not all processor OS combinations may use the same address for
the access routine.

Fortran: Fix rejecting class arrays of different ranks as storage association argument and add un/pack_class. [PR96992]

Removing the assert in trans-expr, lead to initial strides not set
which is now fixed.  When the array needs repacking, this is done for
class arrays now, too.

Packing class arrays was done using the regular internal pack
function in the past.  But that does not use the vptr's copy
function and breaks OOP paradigms (e.g. deep copy).  The new
un-/pack_class functions use the vptr's copy functionality to
implement OOP paradigms correctly.

The recent move of libgfortran object files to subdirs and the resulting
breakage of libgfortran.so symbol exports demonstrated how fragile
deriving object and archive names from their libtool counterparts in the
Makefiles is.  Therefore, this patch moves that step into
make_sunver.pl, considerably simplifying the Makefile rules to create
the version scripts.

Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11, verifying that the version scripts are identical
except for the input filenames.

With the change in subdirectories, the code for libgfortran fat libraries
needs to be adjusted to explicitly reference the subdirectory.  AIX
creates fat library archives and the compiler itself can be built as
either 32 bit or 64 bit application and default code generation.  For
the two, alternate versions of the compiler to interoperate, GCC needs
to construct the fat libraries manually.

The Makefile fragment had been trying to leverage as much of the existing
targets and macros as possible.  With the subdirectory change, the
location of single.o is more obscured and cannot be determined without
libtool.  This patch references the location of the real object file
more explicitly.

Utilizing subst seems like overkill and unnecessary obscuration for a single
object file.  Either way, it's digging below the libtool abstraction layer.

This also fixes Fortran bootstrap on AIX.

The move of libgfortran objects to subdirectories completely broke the
creation of libgfortran.so on Solaris.  Since the gfortran.ver-sun rule
doesn't support that structure, no libtool objects are found, thus no
symbols exported from libgfortran.so, causing every link to fail.

This patch fixes this by allowing for the new structure.

Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11.
