Improve sidebar styling to make its integration easier
Part of https://github.com/rust-lang/docs.rs/issues/417
Setting the height was an error: forcing the element bottom to be at the bottom allows to change to top of the sidebar.

Fully clear `HandlerInner` in `Handler::reset_err_count`
Address [`FIXME`](702b45e409/src/librustc_errors/lib.rs (L472)) for `Handler::reset_err_count` in the way suggested by @Mark-Simulacrum, i. e. clear all the fields of `HandlerInner`.

Fix zebra-striping in generic dataflow visualization
A small formatting improvement to #64828.
Prior to this, the background color of the first row of the table for each basic block changed seemingly at random. You can see this in [basic block #5](https://github.com/rust-lang/rust/pull/64828#issuecomment-536690047) under "New table". Now it is always light.
This also updates the example table to match the current output.
use try_fold instead of try_for_each to reduce compile time
as it was stated in #64572 that the biggest gain was due to less code was generated I tried to reduce the number of functions to inline by using try_fold direct instead of calling try_for_each that calls try_fold.
as there is some gains with using the try_fold function this is maybe a way forward.
when I tried to compile the clap-rs benchmark I get times gains only some % from #64572
there is more function that use eg. fold that calls try_fold that also can be changed but the question is how mush "duplication" that is tolerated in std to give faster compile times
can someone start a perf run?

SelfProfiler API refactoring and part one of event review
This PR refactors the `SelfProfiler` a little bit so that most profiling methods are RAII-based. The codegen backend code already had something similar, this refactoring pulls this functionality up into `SelfProfiler` itself, for general use.
The second commit of this PR is a review and update of the existing events we are already recording. Names have been made more consistent. CGU names have been removed from event names. They will be added back in when function parameter recording is implemented.
There is still some work to be done for adding new events, especially around trait resolution and the incremental system.

Avoid `chain()` in `find_constraint_paths_between_regions()`.
This iterator can be hot, and chained iterators are slow. The second
half of the chain is almost always empty, so this commit specializes the
code to avoid the chained iteration.
This change reduces instruction counts for the `wg-grammar` benchmark by
up to 1.5%.
Make all alt builders produce parallel-enabled compilers
We're not quite ready to ship parallel compilers by default, but the alt
builders are not used too much (in theory), so we believe that shipping
a possibly-broken compiler there is not too problematic.

syntax: cleanup param, method, and misc parsing
Do some misc cleanup of the parser:
- Method and parameter parsing is refactored.
- A parser for `const | mut` is introduced that https://github.com/rust-lang/rust/pull/64588 can reuse.
- Some other misc parsing.
Next up in a different PR:
- ~Implementing https://github.com/rust-lang/rust/issues/64252.~ -- maybe some other time...
- Heavily restructuring up `item.rs` which is a mess (hopefully, no promises ^^).

BTreeSet intersection, is_subset & difference optimizations
...based on the range of values contained; in particular, a massive improvement when these ranges are disjoint (or merely touching), like in the neg-vs-pos benchmarks already in liballoc. Inspired by #64383 but none of the ideas there worked out.
I introduced another variant in IntersectionInner and in DifferenceInner, because I couldn't find a way to initialize these iterators as empty if there's no empty set around.
Also, reduced the size of "large" sets in test cases - if Miri can't handle it, it was needlessly slowing down everyone.

Deduplicate closure type errors
Closure typing obligations flow in both direcitons to properly infer
types. Because of this, we will get 2 type errors whenever there's
an unfulfilled obligation. To avoid this, we deduplicate them in the
`InferCtxt`.
