FIXME: The following static functions are SizeChangeStrategy functions that are meant to temporarily mimic the behaviour of the old legalization based on doubling/halving non-legal types as closely as possible.

This is not entirly possible as only legalizing the types that are exactly a power of 2 times the size of the legal types would require specifying all those sizes explicitly. In practice, not specifying those isn't a problem, and the below functions should disappear quickly as we add support for legalizing non-power-of-2 sized types further.
