re PR fortran/88929 (ICE on building MPICH 3.2 with GCC 9 with ISO_Fortran_binding)

2019-01-24  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/88929
	* trans-array.c (gfc_conv_descriptor_elem_len): New function.
	* trans-array.h : Add prototype for above.
	* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Take account of
	assumed rank arrays being flagged by rank = -1 in expressions.
	Intent in arrays need a pointer to a copy of the data to be
	assigned to the descriptor passed for conversion. This should
	then be freed, together with the CFI descriptor on return from
	the C call.
