Now that we have generic --enable-address|undefined|memory-sanitizer
options, let the user pick one of these instead of making the fuzzer
enable one implicitly.
This is an end-to-end fuzzer that executes arbitrary PHP code.
We replace the executor with a finite-step executor to avoid
getting stuck in loops or recursion.
Unlike the straight unserialize fuzzer, this runs only on HashContexts,
and it does an update and finalize on the contexts it creates.

* Avoid an unnecessary -lstdc++ dependency. It's not going to be
used in the end anyway, and is an unnecessary hassle to set up.
* Use $LIB_FUZZING_ENGINE instead of hardcoding -lFuzzingEngine.
