maint: Clean up compile warnings in liboctave from cset 7cac4e7458f2.

* Sparse.h (range_error): Mark function with OCTAVE_NORETURN attribute.
* Sparse.h (read_sparse_matrix): "return is" at end of fcn.

* dSparse.cc (tinverse): Delete unused inverse_singular label.

* idx-vector.h (as_array, sort_idx): Mark function with OCTAVE_NORETURN.

* Quad.h (do_integrate): Mark unreachable do_integrate combinations
with OCTAVE_NORETURN.
