* Add a sibling interface to InterpreterAssembler called CodeStubAssembler which provides a wrapper around the RawMachineAssembler and is intented to make it easy to build efficient cross-platform code stubs. Much of the implementation of CodeStubAssembler is shamelessly stolen from the InterpreterAssembler, and the idea is to eventually merge the two interfaces somehow, probably moving the InterpreterAssembler interface over to use the CodeStubAssembler. Short-term, however, the two interfaces shall remain decoupled to increase our velocity developing the two systems in parallel. * Implement the StringLength stub in TurboFan with the new CodeStubAssembler. Replace and remove the old Hydrogen-stub version. * Remove a whole slew of machinery to support JavaScript-style code stub generation, since it ultimately proved unwieldy, brittle and baroque. This cleanup includes removing the shared code stub context, several example stubs and a tangle of build file changes.

CallIC and CallConstructStub look so alike, at least in the feedback they gather even if the implementation differs...and CallIC has such a nice way of surfacing the feedback (CallICNexus), that there is a request to make CallConstructStub look analogous.

This is the initial step towards refactoring the regexp literation creation code to make it less obscure and more similar to the mechanism we use to create array and object literals. There's now a new runtime entry %CreateRegExpLiteral with the same interface as the entries for array and object literals, except that we still pass the flags as string. Instead of embedding the hand written native to clone JSRegExp instances we now have a FastCloneRegExpStub, which behaves similar to the other FastCloneShallowArrayStub and FastCloneShallowObjectStub that we already had.

There's no point in collecting feedback for super constructor calls, because in all (interesting) cases we can gather (better) feedback from other sources (i.e. via inlining or via using a LOAD_IC to get to the [[Prototype]] of the target). So CallConstructStub is now only used for new Foo(...args) sites where we want to collect feedback in the baseline compiler. The optimizing compilers, Reflect.construct and super constructor calls use the Construct builtin directly, which allows us to remove some weird code from the CallConstructStub (and opens the possibility for more code sharing with the CallICStub, maybe even going for a ConstructICStub). Also remove the 100% redundant HCallNew instruction, which is just a wrapper for the Construct builtin anyway (indirectly via the CallConstructStub). Drive-by-fix: Drop unused has_function_cache bit on Code objects.

This changes the interface descriptor for the arguments adaptor to also contain an explicit register for the new.target value. Note that the stub still clobbers the register for now. This is a preparatory CL to allows us passing new.target in a register instead of via a side-channel through the construct stub frame.

The StringCompareStub used to take its parameters on the (JavaScript) stack, which made it impossible to use in TurboFan. Actually StringCompareStub was currently completely unused. This changes the calling convention to something TurboFan compatible and introduces a CallInterfaceDescriptor for StringCompareStub. It also changes HStringCompareAndBranch to use the StringCompareStub instead of using the full blown CompareICStub for a stupid string comparison.

The semantics of the %_CallFunction intrinsic seem to be very unclear, which resulted in a lot of bugs. Especially the combination with %IsSloppyModeFunction is always a bug, because the receiver would be wrapped in the wrong context. So the %IsSloppyModeFunction helper is gone now, and many of the buggy uses of %_CallFunction are also eliminated. If you ever need to call something with a different receiver, then %_Call is your friend now. It does what you want and implements the call sequence fully (and correct).

The previous hack with HInstanceOfKnownGlobal was not only slower, but also very brittle and required a lot of weird hacks to support it. And what's even more important it wasn't even correct (because a map check on the lhs is never enough for instanceof). The new implementation provides a sane runtime implementation for InstanceOf plus a fast case in the InstanceOfStub, combined with a proper specialization in the case of a known global in CrankShaft, which does only the prototype chain walk (coupled with a code dependency on the known global). As a drive-by-fix: Also fix the incorrect Object.prototype.isPrototypeOf implementation.

This is the initial (big) step towards a more uniform implementation of the ToObject abstract operation (ES6 7.1.13), where we have a fallback implementation in JSReceiver::ToObject() and a fast (hydrogen) CodeStub to deal with the fast case (we should be able to do more cleanup on this in a followup CL). For natives we expose the abstract operation via a %_ToObject intrinsic, also exposed via a macro TO_OBJECT, that unifies the previous confusion with TO_OBJECT_INLINE, ToObject, TO_OBJECT, $toObject and %$toObject. Now the whole implementation of the abstract operation is context independent, meaning we don't need any magic in the builtins object nor the native context.

Up until now the context register was listed explicitly in each stub's CallInterfaceDescriptor. This was problematic, because it was listed first in the list of register parameters--which is fine for Crankshaft, which is more or less built to handle the context as the first parameter-- but not ideal for TurboFan, which adds the context at the end of all function parameters. Now the context register is no longer in the register list and can be handled appropriately by both compilers. Specifically, this allows the FunctionType specified for each CallInterfaceDescriptor to exactly match the parameter register list.
