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.

- 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.

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.

Array.prototype.{every, filter, find, findIndex, forEach, map, some}: Use fresh primitive wrapper for calls.

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.

This prevents an unnecessary deopt-reopt cycle due to type feedback
having been thrown away as part of recompiling with deopt support.
(For non-snapshotted functions this is not an issue.)

Bonus: Add missing space in --trace-ic output, and provide names for
PropertyDescriptor's methods, because passing anonymous functions to
SetUpLockedPrototype frightens and confuses our FuncNameInferrer.

As the register allocator cannot reuse spill slots, SameAsFirst
constraint means that we would have to do an expensive move to a
differen spill slot if we choose to spill. Forcing the operand
