This patch fixes PR97045 - unlimited polymorphic array element selectors.

PR fortran/97045
* trans-array.c (gfc_conv_array_ref): Make sure that the class
decl is passed to build_array_ref in the case of unlimited
polymorphic entities.
* trans-expr.c (gfc_conv_derived_to_class): Ensure that array
refs do not preceed the _len component. Free the _len expr.
* trans-stmt.c (trans_associate_var): Reset 'need_len_assign'
for polymorphic scalars.
* trans.c (gfc_build_array_ref): When the vptr size is used for
span, multiply by the _len field of unlimited polymorphic
entities, when non-zero.
