This saves a bunch of a time and will make distributions smaller, as well as
avoiding filling the implementors page with internal garbage. Turn it back on
with `--enable-compiler-docs` if you want them.
(Crates behind the facade are not documented at all)

This saves a bunch of a time and will make distributions smaller, as well as
avoiding filling the implementors page with internal garbage. Turn it back on
with `--enable-compiler-docs` if you want compiler docs during development.
Crates behind the facade are only documented on nightly/dev builds (where they
can be used).

The RUST_TARGET_STAGE_N rule uses LLVM_LIBDIR_RUSTFLAGS_<target-triple>,
which expands to -L "$(llvm-config --libdir)" when the target-triple is
also a host-triple. Rather than expand to -L "" if llvm-config has not yet
been built, add a dependency on the target llvm-config.
When the target-triple is not a host-triple, the new LLVM_CONFIG_$(2)
dependency should expand to nothing.

LLVM_LIBDIR_<triple> is only defined for host triples, not target triples.
FWIW, the same is true for LLVM_STDCPP_RUSTFLAGS_<triple>, where we
explicitly define it as empty when --enable-llvm-static-stdcpp is not
specified, but it's still undefined for cross-compiled triples.

Currently, target.mk passes -L \"\" when LLVM_STDCPP_LOCATION_$(2) is empty.
This fixes #23287.

This commit is an implementation of [RFC 563][rfc] which adds a new
`cfg(debug_assertions)` directive which is specially recognized and calculated
by the compiler. The flag is turned off at any optimization level greater than 1
and may also be explicitly controlled through the `-C debug-assertions`
flag.
[rfc]: https://github.com/rust-lang/rfcs/pull/563
The `debug_assert!` and `debug_assert_eq!` macros now respect this instead of
the `ndebug` variable and `ndebug` no longer holds any meaning to the standard
library.
Code which was previously relying on `not(ndebug)` to gate expensive code should
be updated to rely on `debug_assertions` instead.
Closes #22492

This commit deprecates the majority of std::old_io::fs in favor of std::fs and
its new functionality. Some functions remain non-deprecated but are now behind a
feature gate called `old_fs`. These functions will be deprecated once
suitable replacements have been implemented.
The compiler has been migrated to new `std::fs` and `std::path` APIs where
appropriate as part of this change.

Strategy: If the end goal is to touch e.g. `stamp.std`, then we first
touch `stamp.std.start_time` before doing anything else. Then when
the receipe finishes, we touch `stamp.std` using the timestamp from
`stamp.std.start_time` as the reference time, and remove
`stamp.std.start_time`.
Fix #6518.

This pulls out the implementations of most built-in lints into a
separate crate, to reduce edit-compile-test iteration times with
librustc_lint and increase parallelism. This should enable lints to be
refactored, added and deleted much more easily as it slashes the
edit-compile cycle to get a minimal working compiler to test with (`make
rustc-stage1`) from
librustc -> librustc_typeck -> ... -> librustc_driver ->
libcore -> ... -> libstd
to
librustc_lint -> librustc_driver -> libcore -> ... libstd
which is significantly faster, mainly due to avoiding the librustc build
itself.
The intention would be to move as much as possible of the infrastructure
into the crate too, but the plumbing is deeply intertwined with librustc
itself at the moment. Also, there are lints for which diagnostics are
registered directly in the compiler code, not in their own crate
traversal, and their definitions have to remain in librustc.
This is a [breaking-change] for direct users of the compiler APIs:
callers of `rustc::session::build_session` or
`rustc::session::build_session_` need to manually call
`rustc_lint::register_builtins` on their return value.
This should make #22206 easier.

This patch adds the necessary pieces to support rust on Bitrig https://bitrig.org

After making `rustc` fail on errors at a stop point, like `-Z parse-only`, in #22117, the files in this PR also fail during the parse stage and should be moved as well. Sorry for spliting this move up in two PRs.

- Now "make check-stage2-T-aarch64-linux-android-H-x86_64-unknown-linux-gnu" works (#21773)
- Fix & enable debuginfo tests for android (#10381)
- Fix & enable more tests for android (both for arm/aarch64)
- Enable many already-pass tests on android (both for arm/aarch64)

`cp -a` is a GNU extension. Use an alternate combinaison of POSIX options
(`-PRp`) that do nearly the same.
The difference is `-a` will preserve context, links and xattr attributes,
whereas `-p` not. But as we use it only for copy a file, there is no
difference in the current context.

This is a patch for #22291.
PLEASE_BENCH=1 adds --bench to the arguments passed to the executable to be tested. At the moment, compiletest does not accept a --bench argument, because it is not needed for any test in src/test/, even the tests in src/test/bench do not use #[bench].
I have updated the makefile to only add the --bench flag for crate tests. I do not think that changing compiletest add --bench to the run arguments of all compile tests makes sense, because it would mess up tests which check command line arguments. Also the bench option can be added as comment in a compile test as well.

Highlights:
* Adds an 'uninstall.sh' script to `/usr/local/lib/rustlib/uninstall.sh`, the path to which is printed during installation.
* Components can be deselected during install, like `install.sh --without=rust-docs`.
* Components can be listed with `install.sh --list-components`.
* Vastly reduces spew during install (but supporting a `--verbose` option).
Typicall install run looks like:
```
brian@brianX1:~/dev/multirust⟫ sudo ./install.sh
[sudo] password for brian:
install: creating uninstall script at /usr/local/lib/rustlib/uninstall.sh
install: installing component 'rustc'
install: installing component 'cargo'
install: installing component 'rust-docs'
Rust is ready to roll.
```
Needs to be merged right before corresponding PRs to cargo and rust-packaging.
