Tests for the spec change in https://github.com/dart-lang/language/pull/4655.
- An identifier expression denoting a parameter of a constant primary
constructor that occurs in the initializer list of the body part of the
primary constructor, or in an initializing expression of a non-late
instance variable declaration, is potentially constant.
- A compile-time error occurs if a class, mixin class, enum, or
extension type declaration has a constant generative constructor, and a
non-late instance variable declaration in the body of the declaration
has an initializing expression which is not potentially constant.
- A compile-time error also occurs if the body of a declaration contains
a body part for the primary constructor, and it has an initializer list,
and the initializer list contains an expression which is not potentially
constant.
- A compile-time error occurs if the result of substituting actual
arguments of the constructor invocation into one of the above mentioned
initializing expressions or initializer list elements yields an
expression which is not constant.
