The condition of a Branch or Select can never be a NumberConstant,
because the resulting graph would be invalid, so we don't need to
optimize this case. It can only ever be a tagged boolean or an untagged
bit.

Drive-by-fix: Test the interesting cases in the unit tests instead.

Currently the Typer is installed on the Graph, no matter if we actually
use the types or not (read: even in the generic pipeline). Also the
Typer tries hard to eagerly type nodes during graph building, which
takes time, just to remove those types later again, and retype
everything from scratch. Plus this is inconsistent, since it only
applies to the outermost graph, not the inlined graphs (which are
eagerly typed once the nodes are copied). So in summary, what's
currently implemented is neither useful nor well defined, so for now we
stick to the full typing approach until a proper design for eager typing
is available that will actually benefit us.

Up until now that was still mixed with control reduction in the
ControlReducer. This separation allows us to remove the horrible
Reducer::Finish hack and also do graph trimming at more appropriate
places in the pipeline (i.e. trim dead nodes after generic lowering,
which can also make nodes dead).

isn't the right place to add it (InitializeBody in objects-inl.h also

not being called.

This optimization just duplicates part of the ToBoolean rule in the

AstGraphBuilder::BuildToBoolean() can be optimized easily without types,
especially since the types are only present on some nodes during graph
building. So this optimization is both more efficient and more effective
at the same time. We will probably refactor this code into a separate
optimization method/class later.
