This is a reland of be6bd4f4.
The reason for revert was two bots timing out. On further inspection,
the timeouts seem unrelated.

Original change's description:
> [wasm] Fast paths in EvaluateInitExpression
>
> We add fast paths for the most common types of expressions in
> {EvaluateInitExpression} to improve instantiation time. We fall back to
> full expression decoding for less common operators, or for expressions
> with operands.
