7e50abcc29tests: Add EvalScript(...) fuzzing harness (practicalswift)bebb637472tests: Add FuzzedDataProvider fuzzing helper from the Chromium project (practicalswift) Pull request description: Add `EvalScript(...)` fuzzing harness. To test this PR: We can run `contrib/devtools/test_fuzzing_harnesses.sh` (#17000) during five seconds to quickly verify that the newly added fuzz harness seem to hit relevant code regions, that the fuzzing throughput seems reasonable, etc. `test_fuzzing_harnesses.sh eval 5` runs all fuzzers matching the regexp `eval` giving them five seconds of runtime each. ``` $ CC=clang CXX=clang++ ./configure --enable-fuzz --with-sanitizers=address,fuzzer,undefined $ make $ contrib/devtools/test_fuzzing_harnesses.sh eval 5 Testing fuzzer eval_script during 5 second(s) A subset of reached
