:wave: Hey,
So in #4733 oss-fuzz discovered that we have pretty much been using the wrong instruction formats for all opcodes for a while... (Thanks @jameysharp for digging into this!).
This PR does 2 things:
- Force fuzzgen to use the correct InstructionFormat for each opcode
- Add an assert to all InstructionFormat inserters to ensure that this does not happen again (even for other users of cranelift).
Fixes #4733
