* Move fs::create_dir_all calls into DocFS to provide a clean
extension point if async extension there is needed.
* Convert callsites of create_dir_all to ensure_dir to reduce syscalls.
* Convert fs::write usage to DocFS.write
(which also removes a lot of try_err! usage for easier reading)
* Convert File::create calls to use Vec buffers and then DocFS.write
in order to consistently reduce syscalls as well, make
deferring to threads cleaner and avoid leaving dangling content if
writing to existing files....
* Convert OpenOptions usage similarly - I could find no discussion on
the use of create_new for that one output file vs all the other
files render creates, if link redirection attacks are a concern
DocFS will provide a good central point to introduce systematic
create_new usage. (fs::write/File::create is vulnerable to link
redirection attacks).
* DocFS::write defers to rayon for IO on Windows producing a modest
speedup: before this patch on my development workstation:
$ time cargo +mystg1 doc -p winapi:0.3.7
Documenting winapi v0.3.7
Finished dev [unoptimized + debuginfo] target(s) in 6m 11s
real 6m11.734s
Afterwards:
$ time cargo +mystg1 doc -p winapi:0.3.7
Compiling winapi v0.3.7
Documenting winapi v0.3.7
Finished dev [unoptimized + debuginfo] target(s) in 49.53s
real 0m49.643s
I haven't measured how much time is in the compilation logic vs in the
IO and outputting etc, but this takes it from frustating to tolerable
for me, at least for now.

…ault-to-join, r=sfackler SliceConcatExt::connect defaults to calling join It makes sense to default a deprecated method to the new one. Precedence example is `Error::cause` defaults to calling `Error::source`.
…=kinnison Fix theme-checker failure Fixes rust-lang#61145. I didn't find a way to check it without strongly depending on the output... Is there a way to check if a program fails without checking its output? r? @QuietMisdreavus
… r=alexcrichton rustc-book: Update the rustc/clang compatibility table for xLTO. Firefox is using these combinations successfully.
…arning, r=oli-obk Remove warnings about incr. comp. generating less debugging output. This PR removes the > `-C save-temps` might not produce all requested temporary products when incremental compilation is enabled.` warning and others similar to it. I think these warnings have annoyed lots of people over the past ~3 years; while not helping a single one of them `:P` r? @oli-obk
More NodeId pruning Just another round of the `HirId`ification initiative. r? @Zoxc
