Draft patch - misses modifications to nml_get_addr_expr

The current standard is weird: allocatables/pointers/automatic/non-const-shape
dummy arrays are valid - but only via host/use association. Thus, I postpone
this until there is an official reply from J3/WG5.

I attach a draft patch in order to make sure it won't get lost. The patch goes
past the compile-time check and also past the ICE; however, it does not work as
  nml_get_addr_expr  needs to be modified. One needs to pass the address of the
array data, i.e.  &(array_descriptor.data) rather than &array_descriptor -
which should be done in nml_get_addr_expr. Note: nml_get_addr_expr's
"array_flagged" remains zero for array descriptors. trans-array.c's
gfc_conv_array_data might be a function, which one could use.
