Fuzzer simplification: Remove trap-ignoring logic (#4958)

The "ignore trap" logic there is not close to enough for what we'd need to
actually fuzz in a way that ignores traps, so this removes it. Atm that logic
just allows a trap to happen without causing an error (that is, when comparing
two results, one might trap and the other not, but they'd still be considered
"equal"). But due to how we optimize traps in TrapsNeverHappens mode, the
optimizer is free to assume the trap never occurs, which might remove side
effects that are noticeable later. To actually handle that, we'd need to refactor
the code to retain results per function (including the Loggings) and then to
ignore everything from the very first trapping function. That is somewhat
complicated to do, and a simpler thing is done in #4936, so we won't need
it here.
