Santiago Aboy Solanes fabfa417b4 [ptr-compr] Remove ChangeTaggedSignedToCompressedSigned optimization 
CheckedInt32ToTaggedSigned -> ChangeTaggedSignedToCompressedSigned was
being simplified to CheckedInt32ToCompressedSigned. However, sometimes
the effect chain is not propagated correctly. Since we have plans to
remove the Compressed MachineRepresentation, we can remove this
optimization now.
