I use csmith as the random generator and try to fuzz targets that don't have
any execution fails/ICEs (currently just rv64gcv/rv64gcv_zvl256b).

I was planning on getting the fuzzer and a random config builder running on
spare precommit compute but haven't set it up yet. I'll clean up/put the sh=
ell
scripts I use for csmith here tomorrow:
