* trans-array.c (gfc_conv_expr_descriptor): When building temp,
ensure that the substring reference uses a new charlen.
* trans-expr.c (gfc_conv_aliased_arg): Add the formal intent to
the argument list, lift the treatment of missing string lengths
from the above and implement the use of the intent.
(gfc_conv_function_call): Add the extra argument to the call to
the above.

* trans-array.c (get_array_ctor_var_strlen): Treat a constant
substring reference.
* array.c (gfc_resolve_character_array_constructor): Remove
static attribute and add the gfc_ prefix, make use of element
charlens for the expression and pick up constant string lengths
for expressions that are not themselves constant.
* gfortran.h : resolve_character_array_constructor prototype
added.
* resolve.c (gfc_resolve_expr): Call resolve_character_array_
constructor again after expanding the constructor, to ensure
that the character length is passed to the expression.
