It was accidentally added to debug-only flags. Change-Id: I329d23da5dc31186c27d43eedb021202d2694216 Reviewed-on: https://chromium-review.googlesource.com/899009Reviewed-by:

This creates a uniform PerformPromiseThen builtin, which performs the operation with the same name from the spec, except that it expects the handlers to be either undefined or callable already, since this is only relevant for a single callsite (namely Promise.prototype.then). Introduce a matching operator JSPerformPromiseThen into TurboFan, which represents this operation and removes the additional checks in case of Promise.prototype.then based on the information we can derived from the receiver maps. This yields a nice 20-25% improvement on Promise.prototype.then, as illustrated by the following micro-benchmark ```js const N = 1e7; function inc(x) { return x + 1; } function chain(promise) { return promise.then(inc).then(value => { if (value < N) chain(Promise.resolve(value)); }); } console.time('total'); chain(Promise.resolve(0)); setTimeout(console.timeEnd.bind(console, 'total')); ``` which goes from around 1230ms to 930ms with this patch.

Load mjsunit.js inside the realm as otherwise the functions are not available in the realm's scope. This also prints timestamps after each test to easier track down slow tests. We also pass --omit-quit to not stop too early. This also adds the ability to skip certain tests for endurance fuzzing and skips some tests with known problems.

This makes sure that {JSFunction} invocations always load the code start address into the fixed {kJavaScriptCallCodeStartRegister} register. This allows us to perform PC-relative operations more effective. For now this only applies to code with {kCallJSFunction} linkage.

Pierre Langlois authored
Replace hard-coded uses of `kScratchDoubleReg`, `kScratchDoubleReg2` and `kScratchQuadReg` with the safer `UseScratchRegisterScope`. The reason for doing this is to be able to safely use these scratch registers inside the assembler without having to worry about the code generator using them too. For instance, using this scope showed us that `TryInlineTruncateDoubleToI` is using a FP scratch register while the caller, the `DoubleToI` stub, is using it too. We are safe only because the stub passes the scratch register to `TryInlineTruncateDoubleToI` as an input. Using the scope forces us to explicitely use the input register instead of acquiring a new scratch.

Debug info carries more information than just break points. It also carries debugging-related flags and data for block coverage and type profiling. In production we won't run into the situation where debug info is created with the debugger not enabled. But this way seems a bit more robust.

Instead of inlining NewPromiseCapability everywhere, we should have it as a separate builtin that can be called. The motivation for doing so is to reduce the overhead of the builtins and just share the slow-path handling in a single place, plus this way we can also utilize the NewPromiseCapability functionality from TurboFan optimized code eventually. Also remove the unused %new_promise_capability intrinsic and the builtin backing it.
