Marking on allocation assumes a non-empty stack. Thus marking on
allocation will not finalize even if it runs out of work (we prefer
to finalize in a non-nestable task with no stack).
Instead it will schedule another marking task and delegates
finalization to the next marking task.

Prior to this CL, one had to artificially insert a
basic-block-terminating node after Unreachable. The common pattern was

 Unreachable();
 Goto(&some_label);  // Never reached but generates useless code.

This CL improves usability by automatically merging Unreachable nodes
to the end node, and terminating current effect/control. The updated
pattern is just

 Unreachable();

or in cases where Turboprop must maintain a schedule:

 Unreachable(&some_label);

If the input to a Switch happens to be something that we already know to
be zero-extended, then we don't need to emit a movl to zero-extend it.
This is a tiny optimization, but speeds up the Mono interpreter by 3%
because it's heavily dependent on switch dispatch speed.

With in-place representation changes we can transition from a double
field to a Tagged field without changing the map. So it is not always
safe to assume the loaded value would be a HeapNumber. TurboFan takes a
dependency on the field representation to ensure the code is deoptimized
on any changes. With dynamic map checks, it is not possible to take such
a dependency. Hence check the loaded value is a HeapNumber and
deoptimize otherwise.

The array can be FixedArrayBase, PropertyArray or HeapObject. That
HeapObject has to be either a FixedArray or a PropertyArray since we
have an assert for it. However, due to how the code is structured it
is not so simple to remove HeapObject from the Union.

Drive-by: deleted unused version of BuildFastArrayForEach.

This CL adds a bytes based deadline to draining of worklist.
The time based deadline is also kept because:
1) Unified heap can't transition to bytes-based deadlines yet.
2) Unified heap with concurrent marking needs to flush v8 references
   which don't count as marked_bytes and can cause very long incremental
   pauses.
