Fortran : ICE in gfc_conv_scalarized_array_ref PR53298
When an array of characters is an argument to a subroutine and
is accessed using (:)(1:) an ICE occurs. The upper bound of the
substring does not have an expression and such should not have
a Scalarization State structure added to the Scalarization State
chain.

* trans-array.c (gfc_walk_array_ref): If ref->ss.end is set
call gfc_get_scalar_ss.
