Don't expose Array.prototype.values as it breaks webcompat
Some versions of Outlook Web Access test for the existence of a 'values'
property on Array instances, so adding the 'values' iterator to the prototype

This matches Gecko: they ship Array.prototype.{keys,entries} but not 'values'.

Implement graph trimming in ControlReducer.
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.
This CL is one half of the ControlReducer functionality, the other half
being branch folding.

This adds flags in Scope to track wheter a Scope uses "this" and,
"arguments". The information is exposed via Scope::uses_this(),

usage on any inner scope uses are available as well via
Scope::inner_uses_this(), and Scope::inner_uses_arguments().

Fix out-of-bounds read in SourcePositionToScriptPosition with --hydrogen-track-positions.
We were indexing into the list of inlined functions with inlining ID, which is incorrect.
There can be multiple inlinining IDs corresponding to the same inlined function, because inlining ID is inlining path sensitive unique id for an inlining attempt.
Additionally allow HAbnormalExit to have unknown source position even if we are tracking source positions. No code is generated from abnormal exits anyways.

Better typing and type verification
- Extend verifier to check types of JS and Simplified nodes.
- Untyped nodes now contain NULL as types, enforcing hard failure.
- Typer immediately installs itself as a decorator; remove explicit decorator installation.
- Decorator eagerly types all nodes that have typed inputs
(subsumes typing of constant cache, removing its typing
side-channel and various spurious dependencies on the typer).
- Cut down typer interface to prevent inconsistently typed graphs.
- Remove verification from start, since it caused too much trouble
with semi-wellformed nodes.
- Fix a couple of bugs on the way that got uncovered.
To do: verifying machine operators. Also, various conditions in the
verifier are currently commented out, because they don't yet hold.

Use WeakCell to handle the script wrapper cache
The script wrapper cache used the API weak handles to provide a weak link from Script to ScriptWrapper. We want to change the way API weakness works, and in this context it's best to get rid of users of the API that don't need to be users.

When the receiver is a primitive value, it's cast to an Object before entering the loop. Instead, it should be cast to an Object for each function call while in the loop.
