We shouldn't have shared state between isolates by default. The embedder
is free to pass the same allocator to all isolates it creates.

The goal is to port all of error stack trace formatting to C++.
We will do this bottom up, by first porting helper functions.
Eventually, CallSite methods will only be used when a custom
error stack trace formatter is defined via Error.prepareStackTrace.

Currently only the Win64 bots report this warnings, which adds quite
some overhead to the development process. With this flag we also get
compiler warnings about implicit 64bit to 32bit truncations when
building with clang on Linux/x64 and Mac/x64.

These two test cases "InlineCreateArrayLiteral" and "InlineCreateObjectLiteral" are
added in d1597b7d22. They invokes Linkage::GetStubCallDescriptor
which is unimplemented for turbofan unsupported platform.

...when handing out validity cells to handlers; because invalidating said cells is
the only time we'll need the user registrations.
Along the way, fix a corner case in WeakFixedArray, which can now be empty after
the recently introduced compaction support.
This reverts commit 968715c653.

This uses explicit operators instead of intrinsic runtime calls to
create literals froms boilerplates. It allows for easier access of
static parameters and syncs it with other allocating operators.

This introduces a JSCreateClosure operator which can be lowered by the
typed pipeline to the aforementioned stub. It also allows for further
optimizations of closure creation.

If the array's map is the initial FastHoley array map, and the array prototype
chain is undisturbed and empty of elements, then keyed loads can convert the
load of a hole to undefined.

This reverts commit d5565c1f68.
Getter and setter function names in ES6 are defined as "get foo" and
"set foo".
This also moves the logic for handling symbols from runtime-function.cc
to v8natives.js.

Implements the strong mode proposal's restrictions on
implicit conversions for binary arithmetic operations, not
including the + special case. Adds some infrastructure
for future implementation of the restrictions for other

This introduces a bailout point for class literals right after the
%DefineClass function has been called. Otherwise the FrameState after
class literal evaluation might contain the literal itself.

A strict arrow function with no parameters and no variable bindings
won't need a context object because it will never have any
locals. (This is unlike strict normal functions, which do have
"arguments" and "this" locals.)

Now all nodes that care about deoptimization always take frame state
inputs no matter whether deoptimization is enabled for a particular
function. In case that deoptimization is off, the AstGraphBuilder just
inserts the empty frame state. This greatly simplifies the logic in
various places and makes testing easier as well, and is probably the
first step towards enabling --turbo-deoptimization by default.
There seems to be no noticable performance impact on asm.js programs.
Also fix the graph replay in order to regenerate the scheduler unittests.

ES6 specifies the function name property (it was not part of ES5) and
it specifies the name of Function.prototype to the empty string ("" and
not "Empty"). This makes us match Firefox, Safari and IE developer
