This CL adds two sets of benchmarks.

When given a sticky regexp s.t. lastIndex > subject.length, the following should happen: 1. exec returns null (= no match) 2. lastIndex is reset to 0. This is usually done by the RegExp.p.exec builtin; but in some cases we take different paths and try to re-implement the parts of exec that we need. One of these cases was in %StringReplaceNonGlobalRegExpWithFunction. Here, we set lastIndex to 0 but then incorrectly called into RegExpImpl::Exec. REI::Exec started matching with lastIndex == 0, which is just plain wrong. With this CL we now correctly omit the REI::Exec call and return null.

In order to get a more complete picture about the code sizes of compiled wasm modules, sample the code size of each module after top-tier compilation finished. This happens via the {WasmEngine} because that's where we know which isolates use a given {NativeModule} and can schedule foreground tasks to sample the code size.

The WasmCompileLazy runtime function used to return the start of the instructions of the newly compiled function. With garbage collection of wasm code, it would be tricky to keep this wasm code object alive until it is being called. Thus make the runtime function not return anything, and call via the jump table instead. The jump table was patched as part of lazy compilation to point to the compiled code. Drive-by: Merge {LazyCompileFunction} into single caller {CompileLazy}.

Our UMA data shows a lot of small modules, and I have the suspicion we are loosing some numbers about the bigger ones. Thus sample the module code size after baseline compilation finished. At that point the majority of the code was generated. Sampling after top-tier finished is not that easy since we do not spawn a foreground task at that point.

This is a pre-work for allocating feedback vectors lazily. Feedback cells are required to share the feedback vectors across the different closures of the same function. Currently, they are held in the CreateClosureSlot in the feedback vector. With lazy feedback vector allocation, we may not have a feedback vector. However, we still need a place to store the feedback cells, so if feedback vector is allocated in future it can still be shared across closures.

Currently, if input types are not string or number, ToString builtin will fall into runtime and a loop of ToPrimitive and type-checks is done in runtime, which is slow. This CL reimplements ToString to add support for that ToPrimitive and type-checks loop in CSA instead of runtime to improve performance. This will benefit Array.prototype.toString/join a lot when the array elements are objects. This Cl improves the performance of Speedometer2.0 EmberJS-Debug case by ~14% on Atom.
