Methods of core trait that have doc aliases are found twice

[sugar700]

If you search for a method in core trait that has an alias it appears twice on the list.

For example:

https://doc.rust-lang.org/nightly/std/?search=length

This shows core::iter::ExactSizeIterator::len twice.

This issue is also shown by https://doc.rust-lang.org/nightly/std/?search=reduce.

Relevant code:

rust/src/librustdoc/html/render/cache.rs

Line 83 in 4f4656d

for alias in item.attrs.get_doc_aliases() {

rust/src/librustdoc/formats/cache.rs

Line 322 in 4f4656d

for alias in item.attrs.get_doc_aliases() {

Works for <=, + and presumably all other operators too.

https://doc.rust-lang.org/nightly/std/?search=%2B

Edit: My bad, this is because of the reexport, so it is the same trait but not seen as the same path

Works in core docs too (https://doc.rust-lang.org/nightly/core/?search=%2B), I tested to see if it was the reexport of core from std that did it.

triage: seems like this was "solved" just by removing the doc aliases.
