Refactor Context::Lookup so it is more obvious.  Change the comment in
contexts.h so it no longer indicates that it can return an arguments
object (it can't) and clean up the call sites that had leftover dead code.

"SmartPointer should have been named SmartArrayPointer as it expects an input
allocated using new[] and deallocates it using delete[]. Using it as a simple

When we propagate the information that a value is not convertible to integer,
there is no need for a separate fixed-point computation, we can do things the
"Millikin way" (tm), folding as much computation as possible into a single pass:
;-) We already have the phi node reachability information, so we can easily
propagate this while doing the representation histogram computation.

SmartPointer expects an input allocated using new[] and deallocates it using delete[].

The use-def relation between phis is mainly "forwards" (i.e. from phis with
smaller IDs to ones with larger IDs), so the fixed point computation terminates
faster when iterate through the phis in a "backwards" manner. This is quite
visible in complex Mandreel-generated code, where a few hundred phis with
non-trivial use-def chains are generated.

Duplicate identifier detection must be an early syntax error in strict code,
so errors in otherwise lazily compiled functions must be caught in the
preparser.

The prototype of builtin functions is already unwritable, so we don't
have to make it so (the default map for functions changes after builtins
are initialized).

We no longer need to make the prototype non-extensible, since all properties
that are ever read by the bultins code has been added and frozen already.
Adding properties to the prototype, or changing its __proto__, cannot affect
code.

Removing these two pieces of initialization code reduces the snapshot size
by a few Kb.
