ffi: override libffi size/alignment calculations.

Don't bother creating and filling the ffi_type elements[]
array for a structs or array. Let's punch in the size and
alignment fields with the values we calculate ourselves
already, and set up a dummy elements[] array that contains
only a null terminator.

* ffi.c (struct txr_ffi_type): New member, elements:
one element dummy array that holds a null pointer.
(ffi_type_struct_destroy_op): Do not free ft->elements,
since it isn't dynamically allocated any more.
(ffi_struct_clone, ffi_array_clone): Don't copy the elements
array; just set up a dummy elements array in the copied type.
(make_ffi_type_struct, make_ffi_type_array): Eliminate the
dynamic allocation of the elements array. Point ft->elements
to the dummy array. Set up the ft->size and ft->alignment.
