semantic::Call derives from semantic::Expression, and Type() is the return type of the function
Pull the mutable semantic field from ast::Identifier and into a new semantic nodes.
Have the TypeDeterminer create these new semantic nodes.
Note: This change also fixes the node that holds the semantic information for a call.
Previously this was on the identifier, and this is now correctly on the CallExpression.
The identifier of the CallExpression should resolve to the target function, not the return type.
Functions can currently be represented as a type, and the identifier of a CallExpression now has no semantic information.
