* Remove the `Flags` type from `Config` API This commit removes the final foreign type from the `Config` API in the `wasmtime` crate. The cranelift `Flags` type is now expanded into various options on the `Config` structure itself, all prefixed with `cranelift_` since they're only relevant to the Cranelift backend. The various changes here were: * The `avoid_div_traps` feature is enabled by default since it seemed that was done anywhere anyway. * Enabling the wasm SIMD feature enables the requisite features in Cranelift as well. * A method for enabling the debug verifier has been added. * A method for configuring the Cranelift optimization level, as well as a corresponding enumeration, has been added. * Assert that `Config` is both `Send` and `Sync`
This is the test-programs crate, which builds and runs whole programs
compiled to wasm32-wasi.
