An easy option is to just have a counter inside the enclosing fd and 
increment it each time a local is created.  In D I'd do it with an 
int[string] to track each name independently, but it's probably not worth 
the trouble in C++.  These mangled names are not externally visible and do 
not need to be stable, just unique.
