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.
>
