[objects] Migrate kHoleNanInt64 unboxed doubles to uninitialized values during boilerplate serialization Boilerplate values may possess an unboxed double field filled with the kHoleNan64Int sentinel value, which indicates that the field is uninitialized. When a boilerplate value migrates away from the unboxed double representation to a tagged one, we should replace the sentinel value by the proper uninitialized oddball value. This fixes an issue with JSCreateLowering::AllocateFastLiteral not detecting const stores of uninitialized values properly.

In TurboFan, context specialization is an optimization that tries to either replace the load of a value from the context with a constant, or if that can't be achieved, at least reduce the hops up the context chain by starting a walk to the required depth from the first constant context that it can reach. Currently, this optimization is performed by looking into the heap during a reducer pass. With fully concurrent TurboFan, we need to instead gather information about contexts we may want to perform this optimization on during serialization. This CL adds functionality to the serializer to recognize and model operations that affect the context register. We add to the hinting structure already used by the serializer. There is a new type of hint: a VirtualContext. This is a tuple consisting of a handle to a Context, and a distance field that indicates how far away in a to-be-realized chain this VirtualContext sits from the context in the handle. For example: bytecode stream: ... CreateBlockContext ... After a block context is created, the accumulator now contains a VirtualContext Hint with a distance of 1 from any context hints that we are keeping track of in the current context register.
