Previously, `extractlane` results did not have the expected `uextend` because this work was completed by PEXTRB in x86. Since other architectures may eventually need this and since leaving the `uextend` out leaves the extracted values with the wrong type (`i16` instead of `i32`), the `uextend` is re-added. The duplicated zero-extension work (from PEXTRB and MOVZX) could be fixed by a later optimization.
This crate performs the translation from a wasm module in binary format to the in-memory form of the Cranelift IR.
