We heavily rely on queries and fragments in the URL structure, so
it is desired to preserve them even in the redirects. The generated
redirect pages try to preserve them with scripts, which take
precedence over the original `Refresh` metadata. Non-scripting
browsers would continue to work (with no queries and fragments).
Treat builtin bounds like all other kinds of trait matches. Introduce a simple hashset in the fulfillment context to catch cases where we register the exact same obligation twice. This helps prevent duplicate error reports but also handles the recursive obligations created by builtin bounds.

One negative side-effect of this change is that there might be quite a bit of copying strings out of the codemap, i.e. one copy for every block that gets translated, just for taking a look at the last character of the block. If this turns out to cause a performance problem then `CodeMap::span_to_snippet()` could be changed return `Option<&str>` instead of `Option<String>`.
Fixes#18791
pop calls siftdown, siftdown calls siftdown_range, and siftdown_range
loops on an index that can start as low as 0 and approximately doubles
each iteration.

If the source code is in the parent dirs relative to the crate root, `..` is replaced with `up` as expected. Any other error like non-UTF-8 paths or drive-relative paths falls back to the absolute path.
There might be a way to improve on false negatives, but this alone should be enough for fixing #18370.

* Remove public reexports, as a part of #19253
* Rename getopts::Fail_ to getopts::Fail
* Didn't see a reason for the suffixed '_'
* Removed getopts::FailType
* Looked like it was only beings used for tests; refactored the tests
to stop requiring it
* A few other non-breaking trivial refactoring changes

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`.
