New fuzzer (#1126)
This adds a new method of fuzzing, "translate to fuzz" which means we consider the input to be a stream of data that we translate into a valid wasm module. It's sort of like a random seed for a process that creates a random wasm module. By using the input that way, we can explore the space of valid wasm modules quickly, and it makes afl-fuzz integration easy.
Also adds a "fuzz binary" option which is similar to "fuzz execution". It makes wasm-opt not only execute the code before and after opts, but also write to binary and read from it, helping to fuzz the binary format.
