This reverts commit a241576f. Bytecode array visitor has a side-effect of incrementing the age counter. This patch makes the increment atomic and thus safe for the concurrent marker.

The CASE_BODY macro is inconvenient for debugging, as gdb points only at the SINGLE_CASE line, not the actual expanded line. Converting it into a templatized function should preserve optimization opportunities for the compiler while making debugging much easier.

The quite common empty object literal doesn't need an AllocationSite since it starts off with the general ElementsKind. By using a separate bytecode we can directly instantiate the empty object without jumping to the runtime first. Note: this experimentally disables pretenuring for empty object literals. Depending on the outcome of our benchmarks pretenuring will be enabled again or fully removed for empty object literals.

As specified in Annex B.3.6., initializers are allowed in sloppy mode var declarations in for-in loops. As a consequence, "in" is one of the tokens that can follow an AssignmentExpression - this was not recognized before.

Parse tasks are not currently used, and will need to be changed significantly for background compilation, so we remove them for now.

If a QueryCallback is present, it is used to filter the result from the EnumeratorCallback for enumerable properties. This tests assures that for...in loops work correctly with these interceptors.

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.

In-process capture of exceptions doesn't work well because there's no symbols on-device. Instead, just let the system crashlogger output a backtrace that the run script can symbolize.

This patch removes unnecessary scope creation for C-style, for-in, and for-of loops containing var declarations. Only loops with LET or CONST declarations require additional scoping up-front. After this patch lands, I intend to apply this simplification (as well as that from fa15ba5a) to for-await loops.

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:
