bors 0da6d42f29 Auto merge of #68965 - eddyb:mir-inline-scope, r=nagisa,oli-obk 
rustc_mir: track inlined callees in SourceScopeData.

We now record which MIR scopes are the roots of *other* (inlined) functions's scope trees, which allows us to generate the correct debuginfo in codegen, similar to what LLVM inlining generates.
This PR makes the `ui` test `backtrace-debuginfo` pass, if the MIR inliner is turned on by default.

Also, `#[track_caller]` is now correct in the face of MIR inlining (cc `@anp).`

Fixes #76997.
