Miri side is just a new test, so nothing I could object to. ;) |

Miri has special logic for catching panics during interpretation. Raising a fatal error in rustc uses unwinding to abort compilation. Thus miri ends up catching that fatal error and thinks it saw an ICE. While we should probably change that to ignore
Fatalpayloads, I think it's also neat to continue compilation after a layout query cycle 😆Query cycles now (in addition to reporting an error just like before), return
Err(Cycle)instead of raising a fatal error. This allows the interpreter to wind down via the regular error paths.r? @RalfJung for a first round, feel free to reroll for the compiler team once the miri side looks good
