* trans-array.c (gfc_conv_scalarized_array_ref): If this is a
deferred type and the info->descriptor is present, use the
info->descriptor
(gfc_conv_array_ref): Is the se expr is a descriptor type, pass
it as 'decl' rather than the symbol backend_decl.
(gfc_array_allocate): If the se string_length is a component
reference, fix it and use it for the expression string length
if the latter is not a variable type. If it is a variable do
an assignment. Make use of component ref string lengths to set
the descriptor 'span'.
(gfc_conv_expr_descriptor): For pointer assignment, do not set
the span field if gfc_get_array_span returns zero.
* trans.c (get_array_span): If the upper bound a character type
is zero, use the descriptor span if available.
