0fd7ce99b0 Auto merge of #116010 - RalfJung:more-typed-immediates, r=oli-obk 
interpret: more consistently use ImmTy in operators and casts

The diff in src/tools/miri/src/shims/x86/sse2.rs should hopefully suffice to explain why this is nicer. :)

Don't attempt to compute layout of type referencing error

Leads to more ICEs and strange diagnostics than are worth it.

23f93a1266 Auto merge of #103877 - oli-obk:const_eval_step_limit, r=fee1-dead 
Replace const eval limit by a lint and add an exponential backoff warning

The lint triggers at the first power of 2 that comes after 1 million function calls or traversed back-edges (takes less than a second on usual programs). After the first emission, an unsilenceable warning is repeated at every following power of 2 terminators, causing it to get reported less and less the longer the evaluation runs.
