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.

Apply BOLT optimizations without rebuilding LLVM
This PR adds an explicit BOLT bootstrap step which applies BOLT on the fly when LLVM artifacts are copied to a sysroot (it only does this once per bootstrap invocation, the result is cached). This avoids one LLVM rebuild in the Linux CI dist build.

Make compressed rmeta contain compressed data length after header
Fixes#90056, which is caused by link.exe introducing padding to the `.rustc` section, since it assumes this will have no effect besides allowing it to possibly use the extra space in future links.

Omit unchanged options from config.toml in `configure.py`
Leaves section tags, but removes options that are unchanged.
Change in `config.toml.example` is to prevent comments from sneaking in by being directly after a section tag
closes#108612
Don't call `temporary_scope` twice.
`mirror_expr_inner` calls `temporary_scope`. It then calls `make_mirror_unadjusted` which makes an identical call to `temporary_scope`.
This commit changes the `mirror_expr_inner` to get the `temp_lifetime` out of the expression produced by `make_mirror_unadjusted`, similar to how it currently gets the type.
