`webassemblyjs`'s `instantiate()` does not accept a `WebAssembly.Module`

[jparismorgan]

I noticed that webassemblyjs's instantiate() does not accept a WebAssembly.Module in bufferSource: https://github.com/xtuc/webassemblyjs/blob/master/packages/webassemblyjs/src/index.js#L30

But in the MDN docs, buffersource is allowed to be a WebAssembly.Module:

A typed array or ArrayBuffer containing the binary code of the Wasm module you want to compile, or a WebAssembly.Module.

Would be nice to support this, if possible. Thanks!
