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.
