Currently the Isolate is gotten off of the object that the operation is being performed on. Shared objects return the shared Isolate, which is incorrect as it shouldn't be used to run JS, nor does it have HandleScopes open. Plumb the executing Isolate through.

... which didn't properly handle non-Smi integer indices with JSTypedArray receivers. The addition of new JSReceiver::OrdinaryDefineOwnProperty() overload with LookupIterator::Key caused circular dependency between lookup.h and js-objects.h, so the LookupIterator::Key was moved out of the LookupIterator class in order to make it forward-declarable.

This CL factors out the decision-making logic whether a property key should be treated as a "property" or "element" into LookupIterator::Key, which can be constructed on its own, allowing use sites to take this distinction into account before constructing a LookupIterator from the Key, without needing to duplicate the logic. This also makes the assortment of LookupIterator constructors more uniform.

Inferring the language mode involves iterating the stack to find the closure. This is an expensive operation and should be done only when required. This cl changes the implementation to infer the language mode only when we can't defer it any further. Currently, we infer the language mode when throwing an exception or when passing this information to PropertyCallbackArguments. This cl also changes the language mode parameter to SetProperty related methods to Maybe<ShouldThrow>. We only use the language mode to decide if we need to throw and using ShouldThrow instead of language mode simplifies the code by avoiding conversions from Maybe<ShouldThrow> to Maybe<LanguageMode> and vice-versa.

Abstract equality comparison of a BigInt and a String converts the latter to BigInt. This conversion can fail; since we do not want to pass a context to the comparison function, we must signal such failure without throwing an exception. This CL uses the existing ShouldThrow enum to configure behavior of String-to-BigInt conversion, moving it out of Object into globals.h.

Port the baseline version of Reflect.has to the CodeStubAssembler and reuse the existing logic for HasProperty (i.e. the HasProperty builtin). Also inline the Reflect.has builtin into TurboFan, by adding a check on the target in front of a use of the JSHasProperty operator. Technically this additional check is not necessary, because the JSHasProperty operator already throws if the target is not a JSReceiver, but the exception message is confusing then. This improves the performance of the micro-benchmark from reflectHasPresent: 337 ms. reflectHasAbsent: 472 ms. to reflectHasPresent: 121 ms. reflectHasAbsent: 216 ms. which is a nice 2.8x improvement in the best case. It also improves the chai test on the web-tooling-benchmark by around 1-2%, which is roughly the expected win (since Reflect.has overall accounts for around 3-4%).

Many websites use simple calls to String.prototype.indexOf with either a one character ASCII needle or needles bigger than the search string. This CL adds a TFJ builtin for these simple cases, giving up to factor 5 speedup.
