There was a problem hiding this comment.
Document that these pointers are always "the same" information as the prov argument, just before being taken apart

Rollup merge of rust-lang#138713 - RalfJung:memory-hook-pointers, r=oli-obk interpret memory access hooks: also pass through the Pointer used for the access In some ongoing work on the Miri side, we need the absolute address that the memory access occurred at. That is non-trivial to obtain since we don't have an `ecx`. So pass through the `Pointer` used for the access, which contains the address, and which is available everywhere we are calling these hooks. r? `@oli-obk`
