We want to ensure that all runtime objects are created as soon as compilation finishes. Instead of scheduling another foreground thread to create these runtime objects, we now call it directly from the already executing foreground thread.

I missed one required change which was hidden behind an #if. The fix is in the diff between Patch 1 and Patch 3. Original message: In this CL I remove the isolate from signatures of ExternalReference accessor functions where the isolate is not used. The uses of the isolate were already removed in previous CLs. Changes: * I split the ExternalReference list in external-reference.h into those which need the isolate for initialization and those which do not. * I removed the public constructors and replaced them by ExternalReference::Create(). The reason is to separate external creation more clearly from internal creation, because externally created ExternalReferences sometimes need redirection, whereas internally created ExternalReferences are just stored as they are. In addition, by removing the isolate from the signature of the public constructors, they suddenly exactly matched the interal constructor. * Replace all uses of the public constructors with ExternalReference::Create(). * Remove the isolate from all call sites where necessary. This is a step towards making WebAssembly compilation independent of the isolate.

This CL implements TypedArray.p.sort in Torque. The Torque version works basically the same as the existing JS builtin: When no comparison function is provided, the C++ fast path builtin is used. Otherwise a quicksort written in Torque is used, with a InsertionSort fallback for smaller arrays. The JS quicksort implementation also containes a more elaborate third pivot calculation for larger arrays. This is currently not done. Reported benchmark results are only for those, where a custom comparison function is provided. The numbers for the C++ path stayed the same.

This adds two new UMA histograms to give us more insight into Wasm memory allocation. The first records the result of every attempt to to allocate a Wasm backing store. This will let us know things like how often we explicitly trigger a GC, or how often we hit our address space limit. The second records how many megabytes of address space Wasm reserves. A sample is added every time the number either increases or decreases. This metric will give us a sense of how many outstanding Wasm memories there are in typical usage.

Wasm tier-up first compiles the whole module using Liftoff, and then using Turbofan. The idea is to achieve fast start-up times by first running Liftoff-compiled code. In the meantime we finish compilation with Turbofan, and replace the Liftoff-compiled code as soon as Turbofan finished compilation, thus achieving high performance. Tier-up is enabled through the flag FLAG_wasm_tier_up.

WebAssembly.instantiate is polymorphic, it can either take a module object as parameter, or a buffer source which should be compiled first. To share code between the two implementations, the module object was first passed to a promise (i.e. which is the result of compilation). However, passing the module object to a promise has a side effect if the module object has a then function. To avoid this side effect I remove this code sharing and call AsyncInstantiate directly in case the parameter is a module object.

For use cases with a large number of threads or a large number of isolates (or both), ThreadDataTable can be a major performance bottleneck due to O(n) lookup time of the linked list. Switching to a hash map reduces this to O(1). Example 1: Sandstorm.io, a Node.js app that utilizes "fibers", was observed spending the majority of CPU time iterating over the ThreadDataTable. See: https://sandstorm.io/news/2016-09-30-fiber-bomb-debugging-story Example 2: Cloudflare's Workers engine, a high-multi-tenancy web server framework built on V8 (but not Node), creates large numbers of threads and isolates per-process. It saw a 34x improvement in throughput when we applied this patch. Cloudflare has been using a patch in production since the Workers launch which replaces the linked list with a hash map -- but still global. This commit builds on that but goes further and creates a separate hash map and mutex for each isolate, with the table being a member of the Isolate class. This avoids any globals and should reduce lock contention. Bug: v8:5338 Change-Id: If0d11509afb2e043b888c376e36d3463db931b47 Reviewed-on: https://chromium-review.googlesource.com/1014407Reviewed-by:
