Generates API graph edges in two cases:

  • When an object escapes, generates getMember edges to the return-value of getters.
  • When an instance of a class escapes, generates getMember edges to the instance members of the class (including getters, as above).
    • Previously, such edges were generated only when the class itself escapes, not when an instance of the class escapes.

Makes the example in #8606 actually work in JS.

Evaluation looks reasonable.

Suggested change
myMethod(x) { /* use (parameter 0 (member myMethod (parameter 0 (member exports (module foo))))) */
myMethod(x) { /* use=moduleImport("foo").getMember("exports").getParameter(0).getMember("myMethod").getParameter(0) */

I recently changed the testing syntax.
All your tests need to be rewritten to the new syntax, because currently they don't test anything.
