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
being branch folding.

usage on any inner scope uses are available as well via

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.

[arm] Drop SMMLS support.
...
Apparently
SMMLS r, b, c, a
computes
r = ((a << 32) - b * c) >> 32
while the documentation is kinda misleading and states that it should
compute
r = a - ((b * c) >> 32)
The actual behavior is kinda useless, so we drop the instruction again.

Fix scheduler to correctly schedule nested diamonds.
...
The scheduler rewires control based on the last *control*
node that appears in the schedule of a block. This is not
sufficient to account for dependencies.
This patch adds additional dependencies to floating control
nodes. Given a floating control node A, every non-control
dependency of every node B that depends on A is introduces
as an additional dependency of A.
This allows the scheduler to correctly schedule two
diamonds A, B, if their only correct schedule is to
schedule B into the ifTrue successor in A.
