Rather than lumping in parsing, bytecode compilation and optimized
compilation all into the same VM "compile" state, seperate them out
into individual states. Additionally, add support for these states
to tickprocessor and profview.

Previously we could not support these due to their unique memory layout
including off-heap backing store allocations. We now serialize these
allocations and then fix-up references to them in the PostProcess step
of deserialization.

This was suggested by bmeurer after running into the confusing
example of:
x => {x:x}
which might appear to be an arrow function that returns an object
literal containing its argument, but instead is an arrow function
that does nothing.
While it's unclear whether the language would change to make this
probable programmer error an actual syntax error, we can at least
gather some data on the question of whether we see any such code
in the wild.

(and SIZE_MAX and INT_MAX are both incorrect).

Asynchronous context tracking mechanisms in Node.js need to store some
state on all promise objects. This change will allow embedders to
configure the number of internal fields on promises as is already done
for ArrayBuffers.

TryHandleSignal was originally limited by conditional compilation to only
platforms where the WebAssembly trap handler is supported. This caused build
problems, because not all the macros we needed were defined everywhere.
Instead, we make TryHandleSignal available on all POSIX platforms, but it
unconditionally returns false if the trap handler is not supported.

Most of the plumbing is already present in the non-public API. According to
ES2016, Symbols are also accepted in calls to getOwnProperty(), and taking
them is required in Blink for proper record<K,V> WebIDL conversions.

WebAssembly needs to be able to allocate memory with guard regions, which
requires more functionality from the array buffer allocator. This change adds
functions for reserving memory regions and changing the memory protection.
This CL also includes some minor refactoring of the code to free array buffers.

Unify, simplify logic, reduce UTF8 specific handling.
Intend of this is also to have stream views.
Stream views can be used concurrently by multiple threads, but
only one thread may fetch new data from the underlying source.
This together with unified stream view creation is intended to be
used for parse tasks.

The use case for this comes from Node.js where the ability to avoid

When asked for a module that previously failed to compile or

This new API sets a native data property on an object
directly, as Template::SetNativeDataProperty does.
It is similar to Object::SetAccessor, but properties

can be replaced.

What will we get:
- console would be included into snapshot and allow us to reduce time that we spent in contextCreated function (~5 times faster),
- it allows us to make further small improvement of console methods, e.g. we can implement super quick return from console.assert if first argument is true,
- console calls are ~ 15% faster.
