Add some fuzzers to test other data structures. (#1870)
Start using a dictionary for fuzzing (see:
https://llvm.org/docs/LibFuzzer.html#dictionaries).
Remove some dead code.
Fuzzing with debug enabled is not usually a great idea (from performance
POV). Keep the code since it might be useful while debugging.
