Make the constant value of AsCompatible match its type (#4881)

Browse Source 
AsCompatible changes a source instruction's type to a compatible type,
so it also needs its constant value to take on the compatible type.
Otherwise the type of the instruction and its constant value will
differ, which makes moving to the constant value into a lossy
transformation.
