Fix -Z lower_128bit_ops handling of statics
Avoids ICEs such as the following:

> get_optimized_mir: missing MIR for `DefId(8/0:40 ~

Add an option to allow rustdoc to list modules by appearance
The `--sort-modules-by-appearance` option will list modules in the
order that they appear in the source, rather than sorting them
alphabetically (as is the default). This resolves#8552.
Do not display hidden types, fixes issue 23912
Fixes#23912.

(It's the one I was talking about a few days ago, just close it if it's useless.)
nll part 5
Next round of changes from the nll-master branch.
Extensions:
- we now propagate ty-region-outlives constraints out of closures and into their creator when necessary
- we fix a few ICEs that can occur by doing liveness analysis (and the resulting normalization) during type-checking
- we handle the implicit region bound that assumes that each type `T` outlives the fn body
- we handle normalization of inputs/outputs in fn signatures
Not included in this PR (will come next):
- handling `impl Trait`
- tracking causal information
- extended errors

arbitrary_self_types: add support for raw pointer `self` types
This adds support for raw pointer `self` types, under the `arbitrary_self_types` feature flag. Types like `self: *const Self`, `self: *const Rc<Self>`, `self: Rc<*const Self` are all supported. Object safety checks are updated to allow`self: *const Self` and `self: *mut Self`.
This PR does not add support for `*const self` and `*mut self` syntax. That can be added in a later PR once this code is reviewed and merged.

Fix the wrong subtraction in align_offset intrinsic.
Given how the stage0 implementation in #43903 is written, as well as that in the RFC, I suppose the current implementation has a typo.
cc #44488, cc @oli-obk.
rustc: ensure optimized enums have a properly aligned size.
Fixes#46769 by padding the optimized enums wrapping packed data as necessary.
Note that this is not the only way to solve this - on nightly, #46436 makes it easier to fix without adding new padding because of the replacement of `packed` flags with a non-redundant scheme.
But because it can't be backported, the optimal fix will be in a separate nightly-only PR (#46809).
