When a FINAL subroutine is being invoked for a discontiguous array, which can
happen for INTENT(OUT) dummy arguments and for some left-hand side variables
in intrinsic assignment statements, it may be the case that the subroutine
being called was defined with a dummy argument that requires contiguous data.

Extend the derived type descriptions used by the runtime to signify when
a special procedure binding requires contiguity; set the flags accordingly;
check them in the runtime support library, and, when necessary, use a
temporary shallow copy of the finalized array data in the call to the
final subroutine.
