Because the toboolean operator may lower to a builtin call (which is
effectful in turbofan parlance after effect control linearization),
it really should be encoded as a simplified operator, which can
be optimized with respect for the effect chain in linearization.
No new functionality here, rather a furniture rearrangement in
the TurboFan node structure.

So far the JSCallReducer was only able to unfold constant
JSBoundFunction targets for JSCall nodes, which is not the
common case. With the introduction of JSCreateBoundFunction
operator earlier, we can now also recognize calls to bound
functions where the bind happens earlier in the function,
i.e. as the example of
a.map(f.bind(self))
in https://twitter.com/BenLesh/status/920700003974123520, which
is a handy way to use Function#bind. So this transformation
takes a node like
JSCall(JSCreateBoundFunction(bound_target_function,
bound_this,
a1,...,aN),
receiver, p1,...,pM)
and turns that into
JSCall(bound_target_function, bound_this, a1,...,aN,p1,...,pM)
allowing TurboFan to further inline the bound_target_function
at this call site if that's also inlinable (i.e. it's a known
constant JSFunction or the result of a JSCreateClosure call).
This improves the micro-benchmark from
arrowCall: 55 ms.
boundCall: 221 ms.
arrowMap: 181 ms.
boundMap: 806 ms.
to
arrowCall: 71 ms.
boundCall: 76 ms.
arrowMap: 188 ms.
boundMap: 186 ms.
so that Function#bind in this case is as fast as using closures,
which is an up to 4.3x improvement in the Array#map example.
