Function getContextFreeTypeOfExpression

test/fixtures/snapshot/typescript.js:79837–79854

* Returns the type of an expression. Unlike checkExpression, this function is simply concerned * with computing the type and may not fully check all contained sub-expressions for errors. * It is intended for uses where you know there is no contextual type, * and requesting

(node)

         * It sets the contextual type of the node to any before calling getTypeOfExpression.
