* trans_array.c (gfc_conv_scalarized_array_ref): Pass the
symbol decl for deferred character length array references.
* trans-stmt.c (gfc_trans_allocate): Keep the string lengths
to update deferred length character string lengths.
* trans-types.c (gfc_get_dtype_rank_type); Use the string
length of deferred character types for the dtype size.
* trans.c (gfc_build_array_ref): For references to deferred
character arrays, use the domain max value, if it is a variable
to set the 'span' and use pointer arithmetic for acces to the
element.
(trans_code): Set gfc_current_locus for diagnostic purposes.

* trans-expr.c (gfc_conv_procedure_call): Do not fix deferred
string lengths of components.

* resolve.c (deferred_op_assign): New function.
(gfc_resolve_code): Call it.
* trans-array.c (concat_str_length): New function.
(gfc_alloc_allocatable_for_assignment): Jump directly to alloc/
realloc blocks for deferred character length arrays because the
string length might change, even if the shape is the same. Call
concat_str_length to obtain the string length for concatenation
since it is needed to compute the lhs string length.
Set the descriptor dtype appropriately for the new string
length.
* trans-expr.c (gfc_trans_assignment_1): Fix the rse string
length for all characters, other than deferred types. For
concatenation operators, push the rse.pre block to the inner
most loop so that the temporary pointer and the assignments
are properly placed.
Backport from mainline.

* trans_array.c (gfc_conv_scalarized_array_ref): Add missing
se->use_offset from condition for calculation of 'base'.
