In the existing implementation, the structured cloning flag is only set at the startup of the renderer process. In other words, if structured cloning or wasm threads are turned on when the renderer process starts up, then structured cloning is enabled. However, with the origin trial for wasm threads it's possible that wasm threads get turned on only later when the webpages loads. With this CL we now always also check the wasm threads flag in addition to checking the structured cloning flag.

There were a lot of tweaks and optimizations to chromium's {base::Optional} implementation. This CL brings us back in sync with that. Some changes were needed to make this compatible with C++11 and with GCC 4.8: 1) Types like std::decay_t and std::enable_if_t were rewritten to use std::decay and std::enable_if. 2) Some conditional no_except declarations were removed. 3) std::is_trivially_copy_constructible and std::is_trivially_move_constructible are assumed to be false on gcc 4 because it's unimplemented there.

For the --async-stack-traces we can also look through initial parts of the promise chain that were created by regular Promise#then() calls to walk up to the first async function frame. This addresses the missing support for aforementioned example ```js (async function() { await Promise.resolve().then(() => console.log(new Error().stack)); })(); ``` which now also works.

When trying to print the scope information for the class fields initializer function, the debugger asks the parser to parse the class literal as a function literal (to get the scope info) ... which doesn't quite work. Instead of adding support for parsing the class literal, we just short cicruit this parsing step by just returning an empty context. This works fine because initializer function doesn't have any variables in it's local scope. The one caveat is that the objects in the scope above this function (like the global) are now missing. This trade off is possibly fine for now, as adding parsing support for class literal to only produce would be a lot of code for not enough use. As a follow up to this change, the devtools UI needs to be updated to handle this empty context cleanly. Currently, it doesn't show the `this` object if no context exists even if the `this` object is correctly passed to the UI from the backend.

The memory pressure notification logic wasn't correct and given the current users of the compiler dispatcher aren't posting speculative tasks, it isn't particularly useful.

There was a small race where an idle task could be posted after the compiler dispatcher had aborted and the CancellableTaskRunner had been cancelled. This was causing flakyness on the bots.

The register allocator has an optimization that makes it try reuse spill-slots between phi-inputs and assign the same spill slot to a phi output, if possible. Furthermore, if the phi has no immediate register use, the output is kept spilled. With this change, no longer require that a phi input was spilled in an immediate predecessor. Instead, it is good enough if it was spilled at definition.

Adds support for enqueuing parallel parse / compile tasks for eagerly compiled IIFEs during parsing. If the --parallel-compile-tasks flag is enabled, the parser will pre-parse eager top-level IIFEs and enqueue a task on the compiler dispatcher to do the actual parsing / compilation on a worker thread. Currently we always enqueue the task, but we likely want to only enqueue parallel tasks where the script has multiple IIFEs or a substantial amount of top-level script code before the IIFE to avoid the main thread having to immediately block on the parallel task. This work will be done as a follow-up. BUG=v8:8041 Change-Id: If68d7c374548cabd4ec32f1fb6752da7d6aaae6b Reviewed-on: https://chromium-review.googlesource.com/c/1275354Reviewed-by:
