wasm2js: run full optimizations during the pipeline (#2071)

We flatten for the i64 lowering etc. passes, and it is worth optimizing afterwards, to clean up stuff they created. That is run if the user ran wasm2js with an optimization level (like wasm2js -O3).

Split the test files to check both optimized and unoptimized code.
