I guess it has been a while since I've run aa32 risu on aa64 host.

The launchpad bug is something that should have been seen from the
beginning, but the similar aa64 operations are expanded as integer
code, not vector code.  The aa32 neon code has only recently been
converted to use gvecs.

The cmle0 (zero) bug has been exposed by the recent constant
propagation improvements; previously we saw a reg/reg compare.
