This macro is used for defining static data members with
STATIC_CONST_MEMBER_DEFINITION. Clang-cl mimics MSVC's
behaviour here, so it also needs __declspec(selectany).
This change was prompted by Clang r237787 which changed
a bug where Clang would previously not emit symbols for
some static data members.

For dumping the number of objects and size of objects alive after the
last gc into chrome://tracing memory dumps, this CL adds new api to
get these number for each isolate.
Note: Chrome should be run with --js-flags='--track_gc_object_stats
--noincremental-marking' for object tracking.

When the page is controlled by a ServiceWorker, the ServiceWorker can return an opaque (non-CORS cross origin) resource response.
We need to treat the messages from such script resource as opaque.

Some of the DevTools' clients need to inspect JS objects without enabling debugger. This CL allows to inspect object's internal properties without enabling debugger and instantiating debug context.
Note that now debug context can be created lazily if v8::Debug::GetDebugContext is called when there is no debug listener. This is fragile and has already resulted in some subtle error. I'm going to fix that in a separate CL.

If there had been no debug listener v8::Debug::GetDebugContext would have created new context and wouln't have kept reference to it. This way we may well end up with several debug contexts and disabled debugger.
As a side effect this change allows to efficiently distinguish debug context from blink contexts by simply comparing handles.

Exposed to the extras as extrasExports (on the builtins object), on
which they can put things that should be accessible from C++. Exposed
to C++ through the V8 API as v8::Context::GetExtrasExportsObject().
Adding a test (in test-api.cc) required adding a simple extra,
test-extra.js, which we build into the standalone builds.

This is first step towards adding V8 heap statistics to the memory
tracing infrastructure. For being able to get useful memory number into
the memory dump, v8 needs to provide an external api needs to obtain
more information about the heap. So, this Cl extends the api to give
information about the memory allocated and used in the spaces.

The embedder can control how many threads it wants to use via the
v8::Platform implementation. V8 internally doesn't spin up threads
anymore. If the embedder doesn't want to use any threads at all, it's
v8::Platform implementation must either run the background jobs on
the foreground thread, or the embedder should specify --predictable

As uClibc defines __GLIBC__ in an attempt to look like glibc, V8_LIBC_GLIBC
was true for uClibc as well. Checking for uClibc before glibc fixes this
and restores the correct behavior.

gcc rejects the following snippet, clang rejects it in -std=c++11 mode:
namespace A { template<class T> class C {}; }
namespace B { template class A::C<int>; }
Indeed, the C++ standard says in 14.7.2p2 "An explicit instantiation shall
appear in an enclosing namespace of its template", so cl.exe is incorrect to
allow this.
Just move the instantiation out of the v8 namespace to fix. No intended
behavior change. Fixes building with clang-cl on Windows.
