This fixes following exception in Sky on attempt to set a breakpoint
"Unhandled: Uncaught ReferenceError: break_point is not defined"
I think this happens in Sky but not in Chrome because Sky scripts are executed in strict mode.

According to ES5 9.5 and 9.6, NaN, -inf, +inf, -0 and 0 all truncate to
zero for both ToInt32 and ToUint32, so we can be a lot smarter in the
typer, loosing less information upon truncation (i.e. x | 0 and x >>> 0).

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.

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.

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.

Don't use the generic algorithm, but instead start going into the
direction of ControlReducer, using a stack plus a revisit queue to
not miss any more possibilities for reductions anymore.

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.
