Avoid constructing the frame summary (and a std::vector) just for getting the function index. Just get it from the code instead (where also the frame summary would get it from).

Tolerance was set to 50 microseconds. This is not enough and causes flaky failures. Tolerance is needed because we record milliseconds and an empty scope can still take a few milliseconds to create and destroy. Increasing the tolerance to 500 microseconds should suffice and makes sense for the test. All expected values are in 10s of milliseconds, so half a millisecond tolerance should be reasonable.

We use a heuristic that tiers up small functions at the first tick to optimize the small functions early. When tiering up from Turboprop it isn't important to tier up these functions quite early since they are already executing optimized code.

Insertion into the map is expensive, hence avoid inserting every single code object. Instead, collect them in a {std::vector}, and only insert them when the {owned_code_} map is being used. By sorting the vector before inserting into the map, we can make most insertions constant time instead of logarithmic in the size of the map, by using the previous insert position as a hint for the next one. Drive-by: Remove an unneeded {WasmCodeRefScope}.

Fix 1: Track Scope::needs_home_object and Scope::uses_super_property accurately. When "eval" is seen, figure out whether it can access "super" and if yes, set the corresponding home object as needed. Fix 2: The object literal scope shouldn't be entered for things inside spreads. Original: https://chromium-review.googlesource.com/c/v8/v8/+/2563275 Previous reland: https://chromium-review.googlesource.com/c/v8/v8/+/2637220 This saves memory (the home object doesn't need to be stored for each method, but only once per class) and hopefully makes the home object a constant in the optimized code.

1) Wasm code is not associated with a Code object, hence WasmFrame::unchecked_code will always return a null object. Hence we can use the default implementation from TypedFrame and avoid the lookup on the heap which will always fail. 2) InternalFrame inherits from TypedFrame, hence can also reuse the unchecked_code implementation from TypedFrame. 3) Use "{}" instead of "Code()" to return "nothing".

This adds a [[WebAssemblyMemory]] internal property to ArrayBuffer and SharedArrayBuffer instances that are owned by WebAssembly.Memory objects. This allows the devtools-frontend to find the WebAssembly.Memory for any given ArrayBuffer, making it possible to properly support WebAssembly.memory.grow() eventually, but also showing a reasonable tab title.

Reason for revert: ClusterFuzz bugs Original change's description: > Reland [super] Store home object in Context instead of JSFunction > > 1) Computed property keys (esp functions in them) shouldn't be inside > the object literal scope. > > 2) I was using an imprecise "maybe uses super" and storing it to > preparse data. This won't fly, since it pollutes sister scopes and > leads to confusion wrt whether an object literal needs a home object > or not. Made it precise (mostly cancelling changes in the original CL). > > 3) PreParser::NewSuperPropertyReference was creating a VariableProxy for > this_function (which made it used) -> inconsistent scopes between > parsing and preparsing. > > 4) MultipleEntryBlockContextScope was messing up the accumulator > > Original: https://chromium-review.googlesource.com/c/v8/v8/+/2563275 > > This saves memory (the home object doesn't need to be stored for each > method, but only once per class) and hopefully makes the home object > a constant in the optimized code. > > Detailed documentation of the changes: > https://docs.google.com/document/d/1ZVXcoQdf9IdMsnRI9iyUjyq9NDoEyx9nA3XqMgwflMs/edit?usp=sharing > > Bug: v8:9237, chromium:1167918, chromium:1167981, chromium:1167988, chromium:1168055 > Change-Id: I4f53f18cc18762c33e53d8c802909b42f1c33538 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2637220 > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Commit-Queue: Marja Hölttä <marja@chromium.org> > Cr-Commit-Position: refs/heads/master@{#72169} TBR=marja@chromium.org,leszeks@chromium.org # Not skipping CQ checks because original CL landed > 1 day ago.
