Previously, Atomics.notify was just an alias to Atomics.wake, which
doesn't quite let us add a use counter for these individual builtins.
This patch refactors the existing Atomics.wake into a separate
function that is called from two separate builtins.

As noted in the attached bug, accurately counting this would require
significant changes to the parser and is thus infeasible.

New code should use nullptr instead of NULL.
This patch updates existing use of NULL to nullptr where applicable,
making the code base more consistent.

By adding a per test source file namespace, we can avoid a lot of
symbol collisions in jumbo builds.
While we're at it, let's remove some "using" statements that also
cause trouble.

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.

This syntax was formerly legal per ECMAScript, but has been a
SyntaxError for some time now. V8 deviates from spec in that it
is instead a runtime error; we'd like to know if we can get
away with removing it (at least in sloppy mode) or if the spec
should be changed.

We deviate from spec in that, in our implementation, __defineGetter__ on non-
configurable properties returns false instead of throwing a TypeError. This commit
adds a use counter to track how often we would be throwing an error we currently
avoid, to determine if we can change to align with spec or if the spec is not
implementable.
