Adam Klein 16943d2d71 Revert "[wasm] Unify deoptimization data" 
This reverts commit 236298acbf.

Reason for revert: suspected cause of failures on GC stress bots:

https://build.chromium.org/p/client.v8/builders/V8%20Mac%20GC%20Stress/builds/16341
https://build.chromium.org/p/client.v8/builders/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot/builds/16269

Original change's description:
> [wasm] Unify deoptimization data
> 
> Add methods to add deoptimization data and use them from all the places
> where we currently add them manually. Also add them to wasm-to-wasm
> wrappers compiled on table set, which was missing before, leading to
> the referenced bug.
> 
> Drive-by: Disable non-applicable MaybeHandle constructors to allow
> overloading functions with different Handle types.

V8 JavaScript Engine

V8 is Google's open source JavaScript engine.

V8 implements ECMAScript as specified in ECMA-262.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

V8 can run standalone, or can be embedded into any C++ application.

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
