5c5c8eb864 Auto merge of #66927 - RalfJung:engines-dont-panic, r=oli-obk 
Miri core engine: use throw_ub instead of throw_panic

See https://github.com/rust-lang/rust/issues/66902 for context: panicking is not really an "interpreter error", but just part of a normal Rust execution. This is a first step towards removing the `InterpError::Panic` variant: the core Miri engine does not use it any more.

ConstProp and ConstEval still use it, though. This will be addressed in future PRs.

From what I can tell, all the error messages this removes are actually duplicates.

2f00e86cb5 Introduce MIR optimizations for simplifying x? on Results. 
This optimization depends on inlining for the identity
conversions introduced by the lowering of the `?`.
To take advantage of `SimplifyArmIdentity`, `-Z mir-opt-level=2`
is required because that triggers the inlining MIR optimization.
