Auto merge of #102570 - cjgillot:deagg-debuginfo, r=oli-obk
Perform simple scalar replacement of aggregates (SROA) MIR opt This is a re-open of https://github.com/rust-lang/rust/pull/85796 I copied the debuginfo implementation (first commit) from `@eddyb's` own SROA PR. This pass replaces plain field accesses by simple locals when possible. To be eligible, the replaced locals: - must not be enums or unions; - must not be used whole; - must not have their address taken. The storage and deinit statements are duplicated on each created local. cc `@tmiasko` who reviewed the former version of this PR.
