...
This is inspired by a recently filed Rust issue noting poor codegen for vector masks (https://github.com/rust-lang/portable-simd/issues/351 ).

[WebAssembly] Explicitly add {z,s}ext so extends are selected
...
During DAG legalization, {u,s}itofp instructions on v2i8, v2i16, v4i8
and v4i16 types ended up being legalized into scalar instructions, when
they could just be extended to v2i32/v4i32 instead.
