Added Neil as a reviewer as I've made some changes to some of his a16 tests. I'm pretty certain that the modifications are correct, but wanted to get feedback on that as well.

I think that we can get rid of adjustWriteMask altogether at some point, but it will require extra support in the instcombine for the image instructions to support TFE/LWE (it just gives up at the moment), but it is definitely wrong to have this code in 2 places. However, we can do that as a separate change - this one is getting quite large already!
