Ben Smith 6a50560650 [wasm] Implement WebAssembly.Global import/export 
The mutable-globals proposal spec allows importing as Numbers or
WebAssembly.Global values, but always exports as WebAssembly.Global.

Since the value is always boxed, we can also import/export i64 values.

This CL also includes support for export of mutable globals. Since the
underlying ArrayBuffer that stores the global's value is shared between
the module and the WebAssembly.Global object, all that needs to be done
is remove the validation check.
