Relax dead condition of array-length.

by implementing instructionMayHaveSideEffects:
as long as the given array is known to be non-null, array-length is
free from side effects---NPE.

It is not removable yet, though, because non-null IR, which informs
the nullability of array, is wiped out before dead code removal.
