Debugging WebAssembly

Wasmtime currently provides the following support for debugging misbehaving WebAssembly:

• We can live debug and step through the guest Wasm on its own.

• We can live debug and step through the guest Wasm and the host at the same time with gdb or lldb.

• When a Wasm guest traps, we can generate Wasm core dumps, that can be consumed by other tools for post-mortem analysis.
