 * Parameters:

 *  @param state — One of the following:
 *      - A WeakMap used to read a private instance field.
 *      - A WeakSet used as an instance brand for private instance methods and accessors.
 *      - A function value that should be the undecorated class constructor used to brand check private static fields, methods, and accessors.
 *  @param kind — (optional pre TS 4.3, required for TS 4.3+) One of the following values:
 *      - undefined — Indicates a private instance field (pre TS 4.3).
 *      - "f" — Indicates a private field (instance or static).
 *      - "m" — Indicates a private method (instance or static).
 *      - "a" — Indicates a private accessor (instance or static).
 *  @param f — (optional pre TS 4.3) Depends on the arguments for state and kind:
 *      - If kind is "m", this should be the function corresponding to the static or instance method.
 *      - If kind is "a", this should be the function corresponding to the getter method, or undefined if the getter was not defined.
 *      - If kind is "f" and state is a function, this should be an object holding the value of a static field, or undefined if the static field declaration has not yet been evaluated.
 * Usage:
 * This helper will only ever be used by the compiler in the following ways:
 *
 * Reading from a private instance field (pre TS 4.3):
 *      __classPrivateFieldGet(<any>, <WeakMap>)

 *
 * Reading from a private instance get accessor (when not defined, TS 4.3+):

 *      NOTE: This always results in a runtime error.
