c177910d92 Fix IC handler cache clearing for JSBuiltinsObject 
The clearing mechanism relies on comparing the cached handler with the installed handler. If we try to preserve monomorphism by pretending that the IC was in uninitialized state, then it will go premonomorphic first, which means on the next miss there's no installed handler available to compare against. Instead, pretend it was premonomorphic, so the comparison will happen right away, will fail as it should, and the cached handler will be cleared.

Thanks to Weiliang for starting the investigation that led to this.

1d4dfd9ac4 [turbofan] Push JSToNumber conversions into Phis. 
This essentially performs the following transformation

  JSToNumber(phi(x1,...,xn,control):primitive)
    => phi(JSToNumber(x1),...,JSToNumber(xn),control):number

which is similar to what we already do for JSToBoolean.

d7e3697ddc harmony-scoping: Implement debugger support for script scope. 
We add a new ScopeType, ScopeType.Script. The scope with
ScopeType.Script is always present in the scope chain (ScopeIterator
fakes it if neededi - i.e. if ScriptContext for a script has not been
allocated since that script has no lexical declarations).
ScriptScope reflects ScriptContextTable.

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.

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.
