* primary.c (match_substring): Add an argument 'deferred' to
flag that a substring reference with null start and end should
not be optimized away for deferred length strings.
(match_string_constant, gfc_match_rvalue): Set the argument.
* trans-expr.c (alloc_scalar_allocatable_for_assignment): If
there is a substring reference return.
* trans-intrinsic.c (conv_intrinsic_move_alloc): For deferred
characters, assign the 'from' string length to the 'to' string
length. If the 'from' expression is deferred, set its string
length to zero. If the 'to' expression has allocatable
components, deallocate them.
