Browse source 
implement SIMD gather/scatter via vector getelementptr

Fixes https://github.com/rust-lang/portable-simd/issues/271

However, I don't *really* know what I am doing here... Cc ``@workingjubilee`` ``@calebzulawski``

I didn't do anything for cranelift -- ``@bjorn3`` not sure if it's okay for that backend to temporarily break. I'm happy to cherry-pick a patch that adds cranelift support. :)
