It would be useful to have libfuzzer generate libfuzzer fuzz targets that could be rolled into Google's OSS fuzzing project:

To fuzz font processing, such as loading glyph outlines, we would like to have two inputs:
1. The usual `data: &[u8]`, mutated from a corpus entry
* data is thus relatively likely to be a somew…

What the title says. libFuzzer does CMP decomp on its own, and our version will weaken the signal to the value profiler.

The libfuzzer for the verifier is only acheiving around 3 iterations per second. With the size of the fuzzing space to be tested, this limits the amount of coverage we can acheive.
Proposal:

I was taking a look at the fuzzer statistics for the Wasmtime project today and noticed that we haven't had any fuzzing since October 15. I wanted to raise this in case it wasn't already known, but if…

NieDzejkob did it back then I think with AFL, but LLVM also has libfuzzer, which seems to be easier to set up.
