```
wasm: fix miscompilation for shifting

This fix ensures that when we are shifting left or right,
both operands have the same WebAssembly type. e.g. it's not possible
to shift a 64 bit integer and 32 bit integer together and will fail
WebAssembly's validator. By first coercing the values to the same
type, we ensure we satisfy the validator.
