Description:
[turbofan] Unify frame state inputs.
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.
