Rollup merge of #101101 - RalfJung:read-pointer-as-bytes, r=oli-obk
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``
