	* gfortran.h (gfc_build_intrinsic_call): New method.
	* expr.c (gfc_build_intrinsic_call): New method.
	* simplify.c (range_check): Ignore non-constant value.
	(simplify_bound_dim): Handle non-variable expressions and
	fix memory leak with non-free'ed expression.
	(simplify_bound): Handle non-variable expressions.
	(gfc_simplify_shape): Ditto.
	(gfc_simplify_size): Ditto, but only in certain cases possible.
