    This reverts commit 6ada6a90.
    
    Reason for revert: Revert for link issue:
    https://bugs.chromium.org/p/v8/issues/detail?id=11335
    
    Original change's description:
    > Reland "Faster JS-to-Wasm calls"
    >
    > This is a reland of 860fcb1b
    >
    > - Disabled the tests for this feature in V8-lite mode (the original
    > change broke V8-lite tests)
    > - Also modified test console-profile-wasm.js that was brittle with this
    > change because it assumed that there was always a JS-to-Wasm wrapper
    > but this is not the case when the TurboFan compilation completes before
    > the Liftoff-compiled code starts to run.
    >
    > More changes in Patchset 8:
    >
    > - Moved inlining of the "JSToWasm Wrapper" away from simplified-lowering,
    > into a new phase, wasm-inlining that reuses the JSInliner reducer.
    > The doc
    > https://docs.google.com/document/d/1mXxYnYN77tK-R1JOVo6tFG3jNpMzfueQN1Zp5h3r9aM/edit#
    > describes the new logic.
    >
    > - Fixed a couple of small issues in wasm_compiler.cc to make sure that
    > the graph "JSToWasm Wrapper" subgraph has a valid Control chain;
    > this should solve the problem we had inlining the calls in functions
    > that can throw exception.

    > Original change's description:
    > > Faster JS-to-Wasm calls
    > >
    > > This replaces https://chromium-review.googlesource.com/c/v8/v8/+/2376165/.
    > >
    > > Currently JS-to-Wasm calls go through a wrapper/trampoline, built on
    > > the basis of the signature of a Wasm function to call, and whose task
    > > is to:
    > > - set "thread_in_wasm_flag" to true
    > > - convert the arguments from tagged types into Wasm native types
    > > - calculate the address of the Wasm function to call and call it
    > > - convert back the result from Wasm native types into tagged types
    > > - reset "thread_in_wasm_flag" to false.
    > >
    > > This CL tries to improve the performance of JS-to-Wasm calls by
    > > inlining the code of the JS-to-Wasm wrappers in the call site.
    > >
    > > It introduces a new IR operand, JSWasmCall, which replaces JSCall for
    > > this kind of calls. A 'JSWasmCall' node is associated to
    > > WasmCallParameters, which contain information about the signature of
    > > the Wasm function to call.
    > >
    > > WasmWrapperGraphBuilder::BuildJSToWasmWrapper is modified to avoid generating code to convert the types for the arguments
    > > of the Wasm function, when the conversion is not necessary.
    > > The actual inlining of the graph generated for this wrapper happens in
    > > the simplified-lowering phase.
    > >
    > > A new builtin, JSToWasmLazyDeoptContinuation, is introduced to manage
    > > lazy deoptimizations that can happen if the Wasm function callee calls
    > > back some JS code that invalidates the compiled JS caller function.
