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. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
