Un-break arm64 isel following 22bae4b1544fc5d82f131ef8fde4cea7666112c2

22bae4b1544fc5d82f131ef8fde4cea7666112c2 introduced an iropt-level rewrite rule

  64to16( 32Uto64 ( x )) --> 32to16(x)

that creates Iop_32to16 nodes.  The arm64 isel apparently has never seen these
before and so asserts.  This is a 1-liner fix.
