  -----------
  [flang] Implement more transformational intrinsic functions in runtime

Define APIs, naively implement, and add basic sanity unit tests for
the transformational intrinsic functions CSHIFT, EOSHIFT, PACK,
SPREAD, TRANSPOSE, and UNPACK.  These are the remaining transformational
intrinsic functions that rearrange data without regard to type
(except for default boundary values in EOSHIFT); RESHAPE was already
in place as a stress test for the runtime's descriptor handling
facilities.

Code is in place to create copies of allocatable/automatic
components when transforming arrays of derived type, but it won't
do anything until we have derived type information being passed to the
runtime from the frontend.
