2eaca10e9b [turbofan] Fix pushing of JSToBooleans into Phis. 
Now we actually implement it the way it is meant to be, that is:

  JSToBoolean(Phi(x1,...,xn):primitive)
    => Phi(JSToBoolean(x1),...,JSToBoolean(xn)):boolean

This also fixes the endless recursion within JSTypedLowering when
the GraphReducer does all possible reductions instead of using the
generic algorithm.

c3af691e72 [turbofan] Remove int32 narrowing during typed lowering. 
With Int32Add we lose the int/uint distinction, so later, in simplified lowering we can make a wrong decision. E.g., see the attached test case, where we lower NumberAdd -> Int32Add because inputs are Uint32, but during simplified lowering we change the inputs to Int32, so we get a wrong result.

Simplified lowering will lower the NumberAdd operations anyway, so we should lose performance.

ef41de10db Classes: Add support for stepping through default constructors 
If a class extends another class and it doesn't provide a constructor,
one is created for them. We therefore need to ensure that stepping into
the constructor steps into the super class constructor.

b17eaaa575 Fix desugaring of let bindings in for loops to handle continue properly 
This requires putting the original loop's body inside an inner for loop (with
the same labels as the original loop) and re-binding the temp variables in its
"next" expression. A second flag is added to the desugared code to ensure the
loop body executes at most once per loop.
