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.

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).

The remaining uses need some non-mechanical work:

  * non-standard-layout type, probably due to mixed access control

This optimization just duplicates part of the ToBoolean rule in the
Typer, and it doesn't make sense to have adhoc partial typing rules in
the ControlReducer anyway.

This invariant will save us some head ache.
The changes to test-debug/DebugStub is due to the fact that it abuses

In ES6, the TypedArray constructor can be called either with an
array-like object or an iterable. The code previously handled
only array-like objects. This patch switches to supporting
iterables while throwing in an optimization to make Arrays
get allocated the old way, without an extra copy.

      The strong-object-set-proto test cases will throw one expected exception
      and the exception message should include the source position in the JS
      file. But crankshaft compiler does not generate the source position for
      it when creating the flow graph by default. The source position information
      is always zero. So it failed when comparing with the reference file.

      If we use crankshaft compiler on IA32 platform to run this test case, it
      has the same failure.

      we will open these test case for x87 once turbofan for X87 is enabled.
