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
