* The WASI targets deal with the `main` symbol a bit differently than native so some `codegen` and `assembly` tests have been ignored. * All `ignore-emscripten` directives have been updated to `ignore-wasm32` to be more clear that all wasm targets are ignored and it's not just Emscripten. * Most `ignore-wasm32-bare` directives are now gone. * Some ignore directives for wasm were switched to `needs-unwind` instead. * Many `ignore-wasm32*` directives are removed as the tests work with WASI as opposed to `wasm32-unknown-unknown`.
