Move the specialization suffix counter and reset it per function, not per specialization.
When we specialize we search for an available function name for specialization. 
We keep a running counter and try a different suffix until we find a free name.
When we specialize a single function multiple times with multiple types we create
work for ourselves because we need to lookup the same name multiple times. 
Resetting the counter per function solves this problem and reduces the compile time.
