This is a reland of 63608968b6
The previous CL failed on Windows, but it was a general bug. The
dropped_elem_segments was not being set on the instance properly in
cctests, so`table.init` instructions would fail by reading uninitialized
data.
I took this opportunity to also add an implementation of
`elem.drop` in the interpreter, and ported the JS tests for those too.
Original change's description:
> [wasm] Implement table.init for interpreter
>
> This also fixes CheckCallViaJS when a trap occurs. In that case, the
> trap callback is called instead of an exception being thrown, so if it
> isn't handled, a bogus result will be returned instead.
