Michael Howell 12dc24f460 rustdoc-search: simplify rules for generics and type params 
This commit is a response to feedback on the displayed type
signatures results, by making generics act stricter.

Generics are tightened by making order significant. This means
`Vec<Allocator>` now matches only with a true vector of allocators,
instead of matching the second type param. It also makes unboxing
within generics stricter, so `Result<A, B>` only matches if `B`
is in the error type and `A` is in the success type. The top level
of the function search is unaffected.

README.md

The tests present here are used to test the generated HTML from rustdoc. The goal is to prevent unsound/unexpected GUI changes.

This is using the browser-ui-test framework to do so. It works as follows:

It wraps puppeteer to send commands to a web browser in order to navigate and test what's being currently displayed in the web page.

You can find more information and its documentation in its repository.

If you need to have more information on the tests run, you can use --test-args:

$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --debug

If you don't want to run in headless mode (helpful to debug sometimes), you can use --no-headless:

$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --no-headless

To see the supported options, use --help.
