This adds a paragraph on how to generate documentation without sloooow `make doc`. I'm not a native English speaker, so there might be some language related bugs (I wish English was as hard to get wrong, as Rust)
This also includes whitespace cleanup of contributing.md in a separate commit. Whiltespace is not significant in github flavored markdown, and my Emacs just cleans ws automatically :)

Our docs were very basic for the various versions of from_utf8, so
this commit beefs them up.
It also improves docs for the &str variant's error, Utf8Error.

By RFC1214:
Before calling a fn, we check that its argument and return types are WF. This check takes place after all higher-ranked lifetimes have been instantiated. Checking the argument types ensures that the implied bounds due to argument types are correct. Checking the return type ensures that the resulting type of the call is WF.
The previous code only checked the trait-ref, which was not enough
in several cases.
As this is a soundness fix, it is a [breaking-change].
Fixes#28609
This PR closes out #28716 and #28735 by making two changes to the compiler:
1. The `--emit` flag to the compiler now supports the ability to specify the output file name of a partuclar emit type. For example `--emit dep-info=bar.d,asm=foo.s,link` is now accepted.
2. The dep-info emission now emits a dummy target for all input file names to protect against deleted files.
These common traits were left off originally by accident from these smart
pointers, and a past attempt (#26008) to add them was later reverted (#26160)
due to unexpected breakge (#26096) occurring. The specific breakage in worry is
the meaning of this return value changed:
let a: Box<Option<T>> = ...;
a.as_ref()
Currently this returns `Option<&T>` but after this change it will return
`&Option<T>` because the `AsRef::as_ref` method shares the same name as
`Option::as_ref`. A [crater report][crater] of this change, however, has shown
that the fallout of this change is quite minimal. These trait implementations
are "the right impls to add" to these smart pointers and would enable various
generalizations such as those in #27197.

This commit is a breaking change for the above reasons mentioned, and the
mitigation strategies look like any of:
Option::as_ref(&a)
a.as_ref().as_ref()
(*a).as_ref()
Previously only keyup event was looked at, which meant that pasting, cutting and
otherwise changing the input without typing would not catch any updates to the
search query.
Please correct me if I confused something but the documentation for ```into_ptr``` and ```into_raw``` of ```CString``` seem to be swapped as the docs for ```into_ptr``` mentions ```into_raw``` and vice versa.
Update: I actually meant ```into_ptr``` and ```into_raw``` NOT ```from_*```
The behavior here isn't really ideal, but we can't really do much better
given the current state of constant evaluation.
The changes to ExprUseVisitor are to avoid a compile error; apparently
that bit of code is extremely sensitive to changes in other areas of the
compiler.
Fixes#28670, and probably a bunch of duplicates.
