The new naming is better. Probably descriptive enough while still avoiding SSE-intrinsic-style acronym salad. The u32 types makes it clear enough that it's about packed values. |

Fixes #707
Wasn't too hot on the GLSL/SPIR-V name of packHalf2x16, it's really confusing to me what the heck that means, so tried to go more explicit with the name - at least to me, f32x2_to_f16x2 is much more clear (and in line with the scalar f32_to_f16 version)
Left off f64 conversion insts for now, ark doesn't need them any time soon and they're weird (I think they're
transmute (u32, u32) <-> f64, not an actual bit-changing conversion?)
