re PR fortran/77325 (ICE in gimplify_var_or_parm_decl, at gimplify.c:1933)

	PR fortran/77325
	* trans-array.c (gfc_alloc_allocatable_for_assignment): If the
	rhs has a charlen expression, convert that and use it.
	* trans-expr.c (gfc_trans_assignment_1): The rse.pre for the
	assignment of deferred character array vars to a realocatable
	lhs should not be added to the exterior block since vector
	indices, for example, generate temporaries indexed within the
	loop.
