These corpora were generated with default libFuzzer flags with 30+ hours of CPU time, and then minimized with: ./fuzz-TARGET -merge=1 -shuffle=0 -prefer_small=1 -use_value_profile=1 corpora/fuzz-TARGET UNMINIMIZED_CORPUS
The following arguments were copied from Bitcoin Core's corpus merging script https://github.com/bitcoin/bitcoin/blob/master/test/fuzz/test_runner.py: -shuffle=0 -prefer_small=1 -use_value_profile=1
The script runs each fuzz target on its seed corpus and prints any failures.
The target builds and runs each fuzz target on its seed corpus.
We want to encourage contributions to the seed corpora that improve coverage.

Updated with 30+ CPU-hours of fuzzing for each seed corpus, and improved corpus merging parameters copied from Bitcoin Core. |

This PR:
/tests/fuzz/corporamake check-fuzztarget to do a regression test of each fuzz target on its seed corpusThis is a first step towards improving our fuzzing practices. See #6083.
Tested:
Note that some of the seeds currently cause failures. I've created #6096 and #6099 to fix those.
