Prior to this CL the CFE verifier would update the type of the
variable in Let expressions from `dynamic` to the computed static type
of the initializer. This CL removes the type update, making the
.expect files reflect the CFE output more accurately. Additionally, a
verification check is added to make sure the static type of the
initializer is assignable to the type of the Let variable.
