* fuzz: add a single instruction module generator As proposed by @cfallin in #3251, this change adds a way to generate a Wasm module for a single instruction. It captures the necessary parameter and result types so that fuzzing can not only choose which instruction to check but also generate values to pass to the instruction. Not all instructions are available yet, but a significant portion of scalar instructions are implemented in this change. This does not wire the generator up to any fuzz targets. * review: use raw string in test * review: remove once_cell, use slices * review: refactor macros to use valtype! * review: avoid cloning when choosing a SingleInstModule

//! Test case generators.

//! Test case generators take raw, unstructured input from a fuzzer
|
|
//! (e.g. libFuzzer) and translate that into a structured test case (e.g. a
|
|
//! valid Wasm binary).
|
|
//!
|

//! These are generally implementations of the `Arbitrary` trait, or some
|
|
//! wrapper over an external tool, such that the wrapper implements the
|
|
//! `Arbitrary` trait for the wrapped external tool.
