This is a key part of avoiding generating conflicting names in our output. To start, RenameVariables now returns a Set of the unique identifier names that exist in the function. Codegen uses this to avoid generating duplicate names for change variables and for the `$` useMemoCache variable. Rather than always emit `$` or `c_N`, codegen checks that this name would not conflict and appends an incrementing suffix until it finds a unique name. Note that it's still possible for us to generate conflicts with global variables, both during RenameVariable and Codegen. The next step will be to avoid conflicts with globals.
