tweaks and fixes for doc(include)
This PR makes a handful of changes around `#[doc(include="file.md")]` (https://github.com/rust-lang/rust/issues/44732):
* Turns errors when loading files into full errors. This matches the original RFC text.
* Makes the `missing_docs` lint check for `#[doc(include="file.md")]` as well as regular `#[doc="text"]` attributes.
* Loads files included by `#[doc(include="file.md")]` into dep-info, mirroring the behavior of `include_str!()` and friends.
* Adds or modifies tests to check for all of these.
incr.comp.: Precompute small hash for filenames to save some work.
For each span we hash the filename of the file it points to. Since filenames can be quite long, especially with absolute paths, this PR pre-computes a hash of the filename and we then only hash the hash.

Prevent rustc overwriting input files
If rustc is invoked on a file that would be overwritten by the
compilation, the compilation now fails, to avoid accidental loss. This
resolves#13019. Kudos to @estebank, whose patch I finished off.
rustc: do not raise the alignment of optimized enums to the niche's alignment.
This is the improved fix for #46769 that does not increase the size of any types (see also #46808).
Fix ICE when calling non-functions within closures
The visitor for walking function bodies did not previously properly
handle error-cases for function calls. These are now ignored,
preventing the panic. This fixes#46771.
Ensure separate activations only occur for assignments to locals
Ensure separate activations only occur for assignments to locals, not projections.
Fix#46746.
(I didn't make a regression test because we do not really have a good way to directly express the case that we are trying to catch, because we cannot write MIR directly.)
syntax: Follow-up to the incorrect qpath recovery PR

rustc: Work around `DICompileUnit` bugs in LLVM
This commit implements a workaround for #46346 which basically just
avoids triggering the situation that LLVM's bug
https://bugs.llvm.org/show_bug.cgi?id=35562 arises. More details can be
found in the code itself but this commit is also intended to ...
Closes#46346
Implement non-mod.rs mod statements
Fixes https://github.com/rust-lang/rust/issues/45385, cc https://github.com/rust-lang/rust/issues/44660
This will fail tidy right now because it doesn't recognize my UI tests as feature-gate tests. However, I'm not sure if compile-fail will work out either because compile-fail usually requires there to be error patterns in the top-level file, which isn't possible with this feature. What's the recommended way to handle this?
NLL feature complete (adds `feature(nll)`)!
This is the final PR for the nll-master branch; it brings over all remaining content.
The contents of the branch include:
- track causal information and use it to report extended errors
- handle `impl Trait` in NLL code
- improve printing of outlives errors
- add `#![feature(nll)]` and some more sample tests
The commits should for the most part build independently.
r? @pnkfelix (and/or @arielb1)
In particular, -Znll might as well imply -Zborrowck=mir by default,
just like `#![feature(nll)]` does.
Also, if NLL is in use, no reason to emit end regions. The NLL pass
just strips them out anyway.
This is more convenient, and allows us to be more independent from
infcx, particularly with respect to `in_progress_tables` field.
No functional change.
