Introduce explicit fast path for allocation from LAB. The slow path refills the LAB and allocates again. Other changes: 1) Move slow path methods out of the header file 2) AllocateRaw(Aligned|Unaligned) are now private methods. All allocations need to go through AllocateRaw for NewSpace now.

These functions match on specific patterns of shuffle that have more optimized implementations. Moving them out of instruction-selector allows us to reuse them in Liftoff. Most of these pattern matching functions do not depend on InstructionSelector, since they work on byte arrays. (The only one is CanonicalizeShuffle, which swaps node inputs.) This is only the first pass of moving those functions out. In particular we can clean things up more by moving the tests out of instruction-selector as well. Those will come in follow-up changes.

As there are not enough registers on ia32 to execute the platform- independent code, the CL also adds ia32-specific code to liftoff-compiler.cc. For this we first retrieve the memory index from the stack, do a bounds check, and calculate the final address. Only afterwards we pop all other values from the stack and pass them to the platform-dependent code.

Out of the four listed reasons, two are obsolete now, since stepping does not modify the code table any more. The first reason also cannot happen any more, since removing a breakpoint will also patch the stack of the isolate, and even if not, removing a breakpoint which is not set will have no effect (not even a stack rewriting). The same applies for the last listed reason. So overall, this code is not needed any more, since it has no effect.

This adds an internal property [[IsDetached]] to the inspector preview of ArrayBuffer instances, which indicates whether the ArrayBuffer was detached (i.e. transfered via `postMessage`). Previously it was rather impossible to tell whether an ArrayBuffer was detached, you had to know that V8 violates the ECMAScript specification and simply sets the byteLength accessor to 0 upon detaching an ArrayBuffer (but even then it was still impossible to tell whether that ArrayBuffer wasn't simply an empty one from the get go).

Allow "iterative" finalization when off-thread finalization is enabled, meaning that each compiled function is finalized immediately after compilation, rather than all functions being first compiled and then finalized. This is what we do on the main thread, and it reduces peak Zone memory usage by being able to discard empty compilation Zones earlier. One necessary functionality for this was being able to defer the finalization of asm.js functions until the main thread pause, since they can't be finalized off-thread -- previously we would just bail out of doing the off-thread finalization if any inner function was asm.js.

When an external string matches and internalized external string, we want to deduplicate them. As part of that de-duplication, we check if either a) the internalized string's resource is null (it's freshly created because the original string was in new space) or b) they point to the same data (in which case we don't want to dispose of the data). However, when doing these checks we cast both the initial and the internalized external string to the same type (one or two byte). So, if a two-byte string finds a one-byte internalized string with equivalent data, this cast will fail. Since we only care about the external string resource being null or equal to another during the above deduplication, the solution is casting first to the more general ExternalString type, comparing resources by address, and only casting to the more specific type when needed (and we know that the types have to match by other construction).
