jay: fix SEL implied pipe

Browse source 
Pretty obscure, but this is not valid:

< (1&W)       sync.nop _.0                                        | $2.dst
< (32&f2.0)   sel.f32 g48, g48, -g40                              | I@7

> (32&f2.0)   sel.f32 g48, g48, -g40                              | @7 $2.dst
