Adds 2 counts to see how often this occurs on the web, both the throwing version (strict mode), and the no-op sloppy mode case, to help determine if the proposal at https://github.com/tc39/ecma262/pull/1307 is web compatible.

This also includes ports of Array.p.toString and Array.p.toLocaleString. Many parts of the old JS implementation are preserved, because TypedArray.p.join still relies on it. These will be removed once TypedArray.p.join is ported to Torque. To simplify implementation, special handling of extremely sparse arrays has been removed. Performance improvements vary by array size, elements, and sparse-ness. Some quick numbers and graphs are here: https://docs.google.com/spreadsheets/d/125VLmRMudk8XaomLCsZQ1ewc94WCqht-8GQwU3s9BW8/edit#gid=2087673710 Cq-Include-Trybots: luci.chromium.try:linux_chromium_headless_rel;luci.v8.try:v8_linux_noi18n_rel_ng;master.tryserver.blink:linux_trusty_blink_rel Change-Id: Ia4069a068403ce36676c37401d349aefc976b045 Reviewed-on: https://chromium-review.googlesource.com/c/1196693 Commit-Queue: Peter Wong <peter.wm.wong@gmail.com> Reviewed-by:

Previously when class names were computed and set as part of StoreDataPropertyInLiteral calls, it was observable to static fields as these static fields are initialized right after the classes were constructed but before the class names were installed. This caused the name property to be undefined for this case. Instead, this patch always forces the creation of a name property on the class constructor when static class fields are used. This patch does kill the class boilerplate optimization, but currently all static class fields are installed using a runtime call to CreateDataProperty so this isn't any worse when using static class fields. In the future, this can be optimized away by storing the name on the boilerplate. There is spec discussion here: https://github.com/tc39/proposal-class-fields/issues/85 There isn't a resolution yet, there's still discussion about whether to have the name be undefined always for static class field initializers. But, I don't think that's useful as it would always kill our boilerplate optimization (like this patch does ..., but without the future optimization potential).

In preparation for sharing RO_SPACE between all Isolates within a process, this first pulls RO_SPACE out of the Startup snapshot and puts it in its own ReadOnly snapshot. The snapshot is first populated with the read-only roots. After that the StartupSerializer serializes as before but starting from the first mutable root. References to objects in the ReadOnly snapshot that aren't themselves roots are added to a new cache called ReadOnlyObjectCache which functions like the PartialSnapshotCache but lives in the ReadOnlySerializer rather than the StartupSerializer. These cache entries are referenced using a new bytecode: ReadOnlyObjectCache. (To make room for this, the ApiReference bytecode has been moved). To reduce code duplication, the StartupSerializer has been refactored to create a new base class RootSerializer, which ReadOnlySerializer also subclasses. The base class is responsible primarily for keeping track of already serialized roots and visiting the roots.

This improves the performance of ExtractFixedArray and CloneFastJSArray for double arrays, which in turn improve the performance of cloning double arrays with slice() or spreading. This, however, does not improve performance of spreading holey double arrays, because spreading needs extra work to convert holes to undefined.

This adds root-relative access in a couple of spots (e.g.: LoadRoot, CompareRoot, PushRoot, Push, Move, etc.). Some methods now dispatch based on whether the given Immediate is an embedded object. ShouldGenerateIsolateIndependentCode() was added as a porting crutch: it forces isolate-independent code for builtins even though the builtin is not in the Builtins::IsIsolateIndependent() whitelist. This allows us to easily figure out which builtins can be white-listed with --print-embedded-builtin-candidates. Newly isolate-independent builtins are now whitelisted. Drive-by: Remove dead CompareRoot and JumpIfRoot helpers.
