This sets us up for getting the wasm code generation off the GC heap. We reference tables as global handles, which have a stable address. This requires an extra instruction when attempting to make an indirect call, per table (i.e. one for the signature table and one for the function table).

The V8 API provides interceptors. They are not part of the EcmaScript specification. But their behavior should be consistent. For example, when an EnumeratorInterceptor is defined, Object.keys(), Object.entries(), and Object.values() should all have the same number of entries. This CL creates consistent behavior among these functions. If a QueryCallback is present, it is used to filter the result from the EnumeratorCallback for enumerable properties.

Currently, Declaration stores a Scope pointer to whichever Scope the declaration appeared in. This is used to disallow var declarations being hoisted over lexical declarations. For example: { let x; { var x; } } But in fact this is the only sort of case where storing the scope is required: for lexical declarations (including function declarations appearing in blocks), Declaration::scope() was always identical to Declaration::proxy()->var()->scope(). That is, only var declarations end up "nested" in this way. This patch adds a subclass of VariableDeclaration to store the Scope. Since the only thing that cares about that data is Scope analysis, this isn't treated as a distinct AstNode::NodeType from VariableDeclaration, leaving all AstVisitors untouched in the process. Also reworked the logic in Scope::CheckConflictingVarDeclarations() for clarity after making changes to accomodate the new code.

Before 983eec89, RewritableExpressions which had been queued for destructuring assignment rewriting but which turned out to be part of a binding pattern in arrow function parameters would be silently ignored by the PatternRewriter. After that CL, they failed with a DCHECK. This patch reverts to the previous behavior, with a TODO to handle this in a better way by dequeuing RewritableExpressions that turned out to be part of an inner arrow function.

Many handlers are not used again, so we can improve the cache hit rate by caching fewer handlers. Specifically, in this CL, when a StoreIC miss causes a new map transition to be created, then the handler is not cached right away yet (it will be cached next time, when the transition exists already). Also, fix an embarrassing bug where growing a TransitionArray dropped cached handlers. That further improves the cache hit rate. ;-) Bug: chromium:752867, chromium:753819 Change-Id: Id8db5ca1e780a5fe8fc61db7f20996e61c65a90e Reviewed-on: https://chromium-review.googlesource.com/619851Reviewed-by:

The TODO was about wrapping together the sourceposition iterator and the bytecode iterator. Since the first one is useful in fewer parts than the second, and the bytecode iterator is more flexible to advance than the sourceposition iterator, and we would not gain that much more readability, this TODO is removed.

This CL is a precursor to the callback-based enumeration of frame summaries. It removes the reliance of FrameInspector on having a cached copy of the FrameSummary, instead unpacking it to instance variables so that clients of FrameInspector do not need to get information from two sources (the FrameSummary and the FrameInspector itself).

The MapGuard node sits in the effect chain as a hint for other optimization passes that a certain value has a certain (set of) map(s) guarded by checks on the control chain. This is useful to learn from explicit control flow inserted for polymorphic property accesses, and then used as part of the polymorphic inlining. This change improves the score on the Octane/DeltaBlue benchmark by around 7-8% and the score on the Octane/Richards benchmark by like 3% on average.
