ecac8b0877 Eliminate special keyed load string stub in favor of uniform handlers.
KeyedLoadIC installs a special case if the receiver is a string.
Although there are several maps for strings, in practice we seem to
be able to treat them individually because a given KeyedLoad site
only sees 1-2 string types.

fe3a8845f0 [turbofan] Correctify typed lowering.
We cannot add new JSToNumber nodes here in general, because:

 a) The inserted ToNumber operation screws up observability of valueOf.
 b) Deoptimization at ToNumber doesn't have corresponding bailout id.

15bc4aa2c8 [turbofan] Run value numbering after SimplifiedLowering.
Running ValueNumberingReducer together with ChangeLowering causes
trouble with the current GraphReducer and makes GVN ineffective, so
running it before we get to change lowering works around that well-known
(phase ordering) problem for now.

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.
