This reverts commit ee4fe8963c.
Reason for revert: <INSERT REASONING HERE>
Original change's description:
> [wasm] trap handlers: fall back on old signal handler
>
> This is primarily needed to test D8 under ASan. ASan installs a signal handler
> early in the process startup to show stack traces from crashes. We need to make
> sure that if V8 does not handle a signal then the existing handler gets a
> chance.
>
> This change only applies when using V8's default signal handler. When
> integrating with the embedder's signal handler the behavior is unchanged.
