bors 14c54b637b Auto merge of #107844 - Zeegomo:no-drop-and-rep, r=cjgillot ... Desugaring of drop and replace at MIR build This commit desugars the drop and replace deriving from an assignment at MIR build, avoiding the construction of the `DropAndReplace` terminator (which will be removed in a following PR). In order to retain the same error messages for replaces a new `DesugaringKind::Replace` variant is introduced. The changes in the borrowck are also useful for future work in moving drop elaboration before borrowck, as no `DropAndReplace` would be present there anymore. Notes on test diffs: * `tests/ui/borrowck/issue-58776-borrowck-scans-children`: the assignment deriving from the desugaring kills the borrow. * `tests/ui/async-await/async-fn-size-uninit-locals.rs`, `tests/mir-opt/issue_41110.test.ElaborateDrops.after.mir`, `tests/mir-opt/issue_41888.main.ElaborateDrops.after.mir`: drop elaboration generates (or reads from) a useless drop flag due to an issue with the dataflow analysis. Will be fixed independently by https://github.com/rust-lang/rust/pull/106430. See https://github.com/rust-lang/rust/pull/104488 for more context		2023-03-05 07:56:26 +00:00
