6fc00b4dea 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.

0e16150d33 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.

3727a10d20 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.

da0c38056f Squeeze the layout of various AST node types. 
The following AST node types were improved (in decreasing number of
importance for asm.js-like source code): Expression, VariableProxy,
Assignment, BinaryOperation, Declaration, Property, Call.

b774d2068b Always compile functions in the snapshot with deoptimization support. 
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.
