This PR lets `rustc` generate debuginfo for variables captured by unboxed closures.
Fixes#19356
@nikomatsakis This PR will probably conflict with #19338. If this gets merged before, you should be able to just leave the test case as it is (maybe remove the `#![feature(unboxed_closures)]` directive).
The previous code was giving an incorrect result (not x/3).
Also, this function does not work with signed integers. It now accepts `u32` instead of `i32`.
The "Returning Pointers" section of the pointers guide broke from the convention of putting code between backticks. This PR fixes that. There's also a little trailing whitespace I took care of.
This fixes a long-time irritant of mine. Inserting tabs causes M-x next-error to not work in emacs and seems to serve relatively little purpose in improving overall readability.

Implements RFC 438.
Fixes#19092.
This is a [breaking-change]: change types like `&Foo+Send` or `&'a mut Foo+'a` to `&(Foo+Send)` and `&'a mut (Foo+'a)`, respectively.

TrieSet doesn't yet have union, intersection, difference, and symmetric difference functions implemented. Luckily, TrieSet is largely similar to TreeSet, so I was able to reference the implementations of these functions in the latter, and adapt them as necessary to make them work for TrieSet.
One thing that I thought was interesting is that the Iterator yielded by `iter()` for TrieSet iterates over the set's values directly rather than references to the values (whereas I think in most cases I see the Iterator given by `iter()` iterating over immutable references), so for consistency within TrieSet's interface, all of these Iterators also iterate over the values directly. Let me know if all of these should be instead iterating over references.
At the same time remove the `pub use` of the variants in favor of accessing
through the enum type itself. This is a breaking change as the `Found` and
`NotFound` variants must now be imported through `BinarySearchResult` instead of
just `std::slice`.

Closes#19271
I stumbled across this today, and it's not really working. It's been around for a very, very long time, and seems to be based on stuff we don't even have anymore.
I asked in `#rust-internals`, and @cmr said we should just kill it, so here I am. :) I don't think that anything else uses Java, but maybe I missed something.
And if this _isn't_ what we want, I'm fine with closing too. Just some housekeeping.
All of the enum components had a redundant 'Type' specifier: TypeSymlink, TypeDirectory, TypeFile. This change removes them, replacing them with a namespace: FileType::Symlink, FileType::Directory, and FileType::RegularFile.
RegularFile is used instead of just File, as File by itself could be mistakenly thought of as referring to the struct.
Part of #19253.
