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.

8a00950303 [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.

0f5949d605 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.

363ac55a5d Script streaming: UTF-8 handling fix. 
The problem was that there can be several multi-byte UTF-8 characters near the
splitting point of the data chunks, and the code didn't handle it properly.

This was also the source of crbug.com/417891 - I thought the crash can only
happen when V8 is passed invalid UTF-8 data, but it can also happen in the
abovementioned case. After the fix, we handle the valid UTF-8 case and also
guard against invalid UTF-8 data.
