interpret: remove an incorrect assertion This fixes an ICE in Miri, [reported](https://rust-lang.zulipchat.com/#narrow/stream/269128-miri/topic/SwitchInt.20with.20no.20targets.3F) by `@saethlin.` The faulty assertion was introduced by https://github.com/rust-lang/rust/commit/432535da2b5144d467056efcfa6864d35ba2de0f, when a previously correct assertion checking that the `otherwise` target exists got replaced by this assertion checking that at least one more target beyond `otherwise` exists. Sadly we don't have a small reproducer so I don't think we can easily add a testcase.

Remove `mir::CastKind::Misc` As discussed in #97649 `mir::CastKind::Misc` is not clear, this PR addresses that by creating a new enum variant for every valid cast. r? ````@oli-obk````

Allow patterns to constrain the hidden type of opaque types fixes #96572 reverts a revert as original PR was a perf regression that was fixed by reverting it: https://github.com/rust-lang/rust/pull/99368#issuecomment-1186587864) TODO: * check if https://github.com/rust-lang/rust/issues/99685 is avoided
2022-09-19Rollup merge of #101985 - RalfJung:generate_stacktrace, r=oli-obkMatthias Krüger-2/+9
interpret: expose generate_stacktrace without full InterpCx In Miri we sometimes want to emit diagnostics without having a full `&InterpCx` available. To avoid duplicating code, this adds a way to get a stacktrace from an arbitrary slice of interpreter frames, that Miri can use with access to just a thread manager.

2022-08-30Rollup merge of #101101 - RalfJung:read-pointer-as-bytes, r=oli-obkDylan DPC-85/+90
interpret: make read-pointer-as-bytes a CTFE-only error with extra information Next step in the reaction to https://github.com/rust-lang/rust/issues/99923. Also teaches Miri to implicitly strip provenance in more situations when transmuting pointers to integers, which fixes https://github.com/rust-lang/miri/issues/2456. Pointer-to-int transmutation during CTFE now produces a message like this: ``` = help: this code performed an operation that depends on the underlying bytes representing a pointer = help: the absolute address of a pointer is not known at compile-time, so such operations are not supported ``` r? ``@oli-obk``

CTFE: exposing pointers and calling extern fn is just impossible The remaining "needs RFC" errors are just needlessly confusing, I think -- time to get rid of that error variant. They are anyway only reachable with miri-unleashed (if at all). r? `@oli-obk`
