* Update the `*.wast` runner to use the `wasmtime` API This commit migrates the `wasmtime-wast` crate, which executes `*.wast` test suites, to use the `wasmtime` crate exclusively instead of the raw support provided by the `wasmtime-*` family of crates. The primary motivation for this change is to use `*.wast` test to test the support for interface types, but interface types is only being added in the `wasmtime` crate for now rather than all throughout the core crates. This means that without this transition it's much more difficult to write tests for wasm interface types! A secondary motivation for this is that it's testing the support we provide to users through the `wasmtime` crate, since that's the expectation of what most users would use rather than the raw `wasmtime-*` crates. * Run rustfmt * Fix the multi example * Handle v128 values in the `wasmtime` crate Ensure that we allocate 128-bit stack slots instead of 64-bit stack slots. * Update to master * Add comment
