This CL applies the same optimization already present for calling API-function. Execution::New and Execution::Call now both check whether the target is an API-function and avoid calling out into the construct/call stub.

This allows us to consume the type hints gathered by the CompareIC for the abstract equality and inequality operators. We need to distinguish Number and NumberOrOddball feedback now, as abstract equality doesn't truncate null and undefined to Number.

Before this change we would first load an 8/16/32-bit value from memory into a 32-bit register, then zero/sign-extend from that register to a 64-bit one. Now we replace that pattern with a single movsx/movzx.

Introduces a new VariableLocation MODULE for variables that live in a module's export table. Scope analysis sets this for the approriate variables. Not yet supported by any backend.

The outer scope of the scope we are compiling doesn't need analysis. Either we're compiling top-level code in which case there is no outer scope. Or we are compiling code at the top-level (eval, function, module), and there won't be anything to resolve in the outer scope. Lastly we could also be compiling with a deserialized scope. In that case the outer scope is already resolved. BUG=v8:5209 Review-Url: https://codereview.chromium.org/2224593002 Cr-Commit-Position: refs/heads/master@{#38419}

Introduce a dedicated MaybeGrowFastElements simplified operator, which tries to grow a fast elements backing store for a given element that should be added to an array/object. Use that to lower a growing keyed store to a sequence of 1) check index is a valid array index, 2) check stored value, 3) maybe grow elements backing store (and deoptimize if it would normalize), and 4) store the actual element. The actual growing is done by two dedicated GrowFastDoubleElements and GrowFastSmiOrObjectElements builtins, which are very similar to the GrowArrayElementsStub that is used by Crankshaft. Drive-by-fix: Turn CopyFixedArray into CopyFastSmiOrObjectElements builtin, similar to the new growing builtins, so we don't need to inline the store+write barrier for the elements into all optimized code objects anymore. Also fix a bug in the OperationTyper for NumberSilenceNaN, which was triggered by this change.

Up until now "-0.0 - x" was lowered in the instruction selector. I moved the lowering now to the MachineOperatorReducer.

This patch folds --optimize-for-size flag and check for low-memory device into Heap::ShouldOptimizeForMemoryUsage() predicate. It has the following side effects: - the heap growing factor for low-memory devices is capped at 1.3 (old value was 2.0). - the memory reducer will be more aggressive for low-memory devices.

- Don't read .constructor when returning a Promise from an async function. Instead, call out to the internals of Promise.resolve directly. This is done by adding back in an "optimization" from an earlier form of the async/await code written by Caitlin Potter. - Async functions always return a new Promise with a distinct identity, even if they simply return another Promise.

Currently we have V8 RuntimeCallStats that is independently from tracing when running d8 with flag --runtime_call_stats. This patch embeds V8 runtime call stats into tracing, by having a global table of runtime call counters each isolate, resetting the table each time we enter a top level trace event, and dumping the table for each top level trace event. This will make trace file more compat, as well as enable runtime call stats in tracing system. This patch adds ~5% overhead to V8 when the category is enabled, we measure the overhead by running a script when category is enabled.
