public class RewriteSingleJsoImplDispatches
extends org.objectweb.asm.ClassVisitor

Effects the renaming of @SingleJsoImpl methods from their original name to their mangled name. Let us call the original method an "unmangled method" and the new method a "mangled method". There are three steps in this process:

1. Within @SingleJsoImpl interfaces rename all unmangled methods to become mangled methods.
2. Within non-JSO classes containing a concrete implementation of an unmangled method, add a mangled method which is implemented as a simple trampoline to the unmangled method. (We don't do this in JSO classes here because the one-and-only trampoline lives in JavaScriptObject$ and is emitted in WriteJsoImpl).
3. Update all call sites targeting unmangled methods to target mangled methods instead, provided the caller is binding to the interface rather than a concrete type.
