We pass to-fixed-length-buffer.any.html and to-resizable-buffer.any.html
but not to-resizable-buffer-shared.any.html, because LibJS doesn't have
growable SharedArrayBuffers implemented...
The spec tells us to reject the promise with a RuntimeError instead of a
LinkError whenever the module's start function fails during module
instantiation. Fixes 1 WPT subtest in `wasm/core`.
There's one failing due to the constructor object not having the name
"Global" vs "WebAssembly.Global". This also doesn't include the
tentative test for the type property.
Add support for shared memory creation in WebAssembly memory API.
This API is needed for WPT tests that use shared array buffers.
