Script streaming: more UTF-8 handing fixes (again).
1) Since we fill the output buffer both from the chunks and the conversion
buffer, it's possible that we run out of space and call CopyCharsHelper with 0
length. The underlying functions don't handle it gracefully, so check there.
2) There was a bug where we used to try to copy too many characters from the
beginning of the data chunk into the conversion buffer. Continuation bytes in
UTF-8 are of the form 0b10XXXXXX. If a byte is bigger than that, it's the first
byte of a new UTF-8 character and we should ignore it.
These two together (or maybe in combination with surrogates) are a probable
reason for crbug.com/420932.
3) The test data was off; \uc481 is \xec\x92\x81.

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

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.
