Previously we only supported strings and not filenames. This
changes the default to filename and adds a new `type: string` which can
be passed `options` to allow for strings to be passed in test code.

The previous change to futex.js will spawn too many workers in d8 in
some test configurations, which will throw an error.
This CL works around that by spawning fewer workers for the
Atomics.notify tests.

At the May 2018 TC39 meeting, they decided to rename Atomics.wake to
Atomics.notify. This change adds Atomics.notify as an alias, but does
not remove Atomics.wake, which will be removed later.
This allows for embedders to use either name to prevent
breaking tests. When the tests are switched over, we can remove
Atomics.wake.

These changes were reverted to improve a perf regression on a Chrome
bot. Since then, the regression has reappeared, then disappeared again
all from seemingly unrelated changes.

This patch refactors the Atomics builtins so that they are implemented
as C++ builtins rather than experimental JS builtins. Previously, each
of these functions called out to a runtime function, so no significant
change in performance is anticipated. The goal of this patch is to
remove the last user of experimental JS builtins so that the mechanism
can be removed, for performance reasons. The patch includes a drive-by
fix of a check-fail. For the most part, the patch is just moving code
without modification from runtime-atomics.cc to
builtins-sharedarraybuffer.cc .

Atomics.wait is a function which may block, which is not allowed on the
main thread. Since V8 doesn't know whether a particular isolate is the
"main thread", this CL adds an option to Isolate::CreateParams to choose
whether this function is allowed.
