With lazy feedback allocation, we don't have feedback vectors when function starts executing. If we mark the function on the first execution we would be missing feedback for the initial part of the function and hence the optimized code will not be useful. This cl resets the optimization markers on OSR if the invocation count of the function is less than 1. We may still do wasted optimizations if the function is hot enough for optimizing but not for OSRing. In the long term we may want to fix it differently. This fix covers the most common cases in benchmarks.

This CL adds an access check for the arguments to all calls to {console} like {console.log}. This is needed since the DevTools protocol notificiation event does not contain the context in which the {console.log} call occurred. Only the context of the argument. When DevTools then reads properties for the preview of the argument, it uses arguments context, instead of the calling context, potentially leaking objects/exceptions into the calling context.

Each LHS expression that contains an optional chain of some form is wrapped in an OptionalChain node. This root node allows us to use a single jump location for every individual item in the chain, improving the performance and simplifying the implementation.

Previous differences in eager and lazy parsing meant that it was possible that feedback vectors could be different for the same function depending on how it was compiled. These issues have now been fixed, so remove the workaround and add an explicit CHECK that the feedback vectors are the same.

This CL introduces a JSAny type for user-exposed JavaScript values and a few new types to define it. Especially, it splits Symbol into PrivateSymbol (not exposed) and PublicSymbol (JavaScript exposed symbols). The change is mostly mechanical, but a few things are interesting: - PropertyKey and JSPrimitive were designed to coincide with the spec notions of IsPropertyKey() and primitive value, respectively. - Since Name is an open type, we define AnyName to be the known subtypes of Name. This is not too elegant, but by using AnyName instead of Name, typeswitch can properly conclude something if a subtype of Name is excluded. Small drive-by changes, which were necessary: - Allow subtyping on label parameters. - Fix the formatting of typeswitch, it was broken with union types in case types.

Currently, the private name symbols are displayed in the block scopes in DevTools, though these are just implementation details of private fields. This patch hides them from the block scope by marking variables with names starting with `#` as synthetic. The private fields are still going to show up in the previews of objects, only the key symbols themselves are going to be hidden.

Instead of inserting "deletion" entries into the store buffer, keep a list of invalidated objects to filter out invalid old-to-new slots. The first CL https://crrev.com/c/1704109 got reverted because both the sweeper and the main task were modifying the invalidated slots data structure concurrently. This CL changes this, such that the sweeper only modifies the invalidated slots during the final atomic pause when the main thread is not running. The sweeper does not need to clean this data structure after the pause, since the "update pointers" phase already removed all invalidated slots.

Sorting is done in order to make compaction more efficient: by sweeping pages with the most free bytes first, we make it more likely that when evacuating a page, already swept pages will have enough free bytes to hold the objects to move (and therefore, we won't need to wait for more pages to be swept in order to move those objects). Since maps don't move, there is no need to sort the pages from MAP_SPACE before sweeping them.

When serializing frame states into translations (later used by deopts), we pass certain values, depending on the frame kind, to be serialized as the frame height. This CL moves the calculation of this height value into the FrameStateDescriptor. In a follow-up, we may want to simplify the way these height values are passed and processed by deopts. The motivation behind this is to simplify calculation of unoptimized stack frame sizes during compilation.
