Add option for local docker testing.
This adds the option `--dev` to `src/ci/docker/run.sh` so that it will enter an interactive environment for local testing. I have often needed this for testing things, but I always needed to edit this script. I wanted the ability to interact in the environment, run different commands, inspect errors, etc.
Use 'tcx for references to AccessLevels wherever possible.
Most of the changes are just fallout from removing a lifetime parameter from structs, and mostly in clippy.

resolve: disallow labelled breaks/continues through closures/async blocks
Fixes#73541.
This PR modifies name resolution to prohibit labelled breaks/continues through closures or async blocks, fixing an ICE. In addition, it improves the diagnostics surrounding labelled breaks/continues through closures or async blocks by informing the user if the label exists in an parent scope and telling them that won't work.

Use WASM's saturating casts if they are available
WebAssembly supports saturating floating point to integer casts behind a target feature. The feature is already available on many browsers. Beginning with 1.45 Rust will start defining the behavior of floating point to integer casts to be saturating as well. For this Rust constructs additional checks on top of the `fptoui` / `fptosi` instructions it emits. Here we introduce the possibility for the codegen backend to construct saturating casts itself and only fall back to constructing the checks ourselves if that is not possible.
Resolves part of #73591
to feature(rc_as_ptr)
These were stabilized alongside the Weak versions,
but having `feature = "weak_.."` on a fn definition
for the non-weak pointers is potentially very confusing.
Remove `TypeckTables::empty(None)` and make hir_owner non-optional.
Each commit before the last one removes uses of `TypeckTables::empty(None)`, replacing the empty tables with having `Option` around the `&'tcx TypeckTables<'tcx>` that HIR visitors kept track of.
The last commit removes the concept of "empty `TypeckTables`" altogether, guaranteeing that every `TypeckTables` corresponds to a HIR body owner.

This commit marks temporaries from MIR construction as internal such
that they are skipped in `sanitize_witness` (where each MIR local is
checked to have been contained within the generator interior computed
during typeck). This resolves an ICE whereby the construction of checked
addition introduced a `(u64, bool)` temporary which was not in the HIR
and thus not in the generator interior.

This commit modifies resolve to disallow `break`/`continue` to labels
through closures or async blocks. This doesn't make sense and should
have been prohibited anyway.
