This adds flags in Scope to track wheter a Scope uses "this" and,

usage on any inner scope uses are available as well via
Scope::inner_uses_this(), and Scope::inner_uses_arguments().

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.

Port r24546 (c3443cd)
Original commit message:
This is required to fix a tricky branch fusion bug on ARM, which was
caused by the interaction between the architecture-independent and
architecture-specific parts of the InstructionSelector. In the end it
wasn't worth sharing a few common lines of code for the additional
complexity, especially if we also want to properly support architectures
without any dedicated flags register (i.e. MIPS).

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.
