:wave: Hey,

This PR allows users to pass a environment variable to fuzzgen that restricts the instructions that it can generate. Passing FUZZGEN_ALLOWED_OPS=ineg,ushr restricts fuzzgen to generate only those two instructions.

Using this allows me to get better fuzzing throughput when testing a specific rule or lowering.

This looks good to me! It would be great to document this, but the most relevant doc I could find is fuzz/README.md. Does that seem like a reasonable place?
