	PR fortran/89843
	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Only
	return immediately if the source pointer is null. Bring
	forward the extraction of the gfc type. Extract the kind so
	that the element size can be correctly computed for sections

	CFI descriptor since this is now done in trans-expr.c.
	(gfc_desc_to_cfi_desc): Only allocate the CFI descriptor if it
	is not null.
	(CFI_section): Normalise the difference between the upper and

	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Use
	the stride measure for the gfc span if it is not a multiple

	* runtime/ISO_Fortran_binding.c (CFI_is_contiguous) : Return
	1 for true and 0 otherwise to comply with the standard. Correct
	the contiguity check for rank 3 and greater by using the stride
	measure of the lower dimension rather than the element length.

	PR fortran/89366
	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc) : In the
	interchange between character and derived, the character type
	was being set incorrectly.
	(gfc_desc_to_cfi_desc) : Eliminate the interchange of types in
	this function. Do not add the kind and length information to
	the type field of structures. Lbounds were incorrectly being
	set to zero for allocatable and pointer descriptors. Should
	have been non-pointer, non-allocatables that received this
	treatment.
