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.

f60bc89083 [turbofan] Make VisitBranch and friends to backend specific. 
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).

b17d131779 AST nodes have at most one bailout/typefeedback ID now, saving lots of memory. 
This is basically https://codereview.chromium.org/569573002/ done right:

During construction, each node type tells its parent how many IDs it
needs in addition to the parent's ones. This is done all the way up in
the class hierarchy until a node's parent doesn't need any ID. At that
point we know how many IDs in summary are needed, and we reserve the
whole range at once, saving only the base ID of that range. All IDs
are now calculated via simple offsets to that base ID. To all
performaniacs: The C++ compiler simplifies the constant calculation to
a simple load and the addition of a single constant.

Note that the actual code is much simpler than all that prose above. :-)
It's basically how compilers for OO languages figure out vtable entries.

We still have lots of holes due to padding in the AST nodes, but this
will be addressed in a separate CL.
