Let’s use generics. You can save a lot of typing by saying that int4/float4/etc are just vec4<isn’t>/etc.

R=me if you add trap, assuming you thread it through everything the obvious way.

How about you add a trap operation, that throws WTrapError the way that we currently do for OOB. 

We should talk about what “trap” means. I think it means that the shader returns prematurely, possibly leaving some output state unpopulated.
