This reverts commit c7a26b13.

Reason for revert: Need to revert previous CL because it fails on MSVC: https://ci.chromium.org/p/v8/builders/ci/V8%20Win64%20-%20msvc/12805

Original change's description:
> [wasm] Do memory.init bounds check in C++ code
> 
> In the existing implementation we first did a bounds check in generated
> code, and then called a simple C++ function to do the actual copying.
> With this CL now we pass the WasmInstanceObject to the C++ function in
> addition to the memory.init parameters. Thereby we can do the bounds
> check in C++, which is much easier, less error prone, and which also
> speeds up code generation and reduces code size. Performance should not
> be worse, because we were already doing the call to C++ anyways.
