Previously the file was not regenrated upon modification of src/rustllvm or others.
Now it will be rebuilt if `src/llvm` or `src/rustllvm` is touched.
Also added *.rs rule to 'clean' rule so that it is removed upon 'make
clean'.
As displayed before this commit, I found the book confusing in its
explanation of `#`-led comments in `rust` blocks. Possibly the
biggest confusion was because the many-dashes construct does not
become an HR element in the Markdown translator used, so things were
not being properly set off.
This change should more clearly show the as-rendered content as
rendered, and the as-coded content as code.
These commits revert https://github.com/rust-lang/rust/pull/28504 and add a regression test pointed out by @petrochenkov, it's not immediately clear with the regression that the accessibility check should be removed, so for now preserve the behavior on stable by default.
r? @nrc
I didn't see anything particularly weird here. The last commit has the only changes I'm not 100% sure about.
I ignored tables.rs since it's genrated, but I updated the python script that generates it.

This PR switches the implemented ordering from `unsafe const fn` (as was in the original RFC) to `const unsafe fn` (which is what the lang team decided on)
As discovered in #29298, `env::set_var("", "")` will panic, but it turns out
that it *also* deadlocks on Unix systems. This happens because if a panic
happens while holding the environment lock, we then go try to read
RUST_BACKTRACE, grabbing the environment lock, causing a deadlock.
Specifically, the changes made here are:
* The environment lock is pushed into `std::sys` instead of `std::env`. This
also only puts it in the Unix implementation, not Windows where the functions
are already threadsafe.
* The `std::sys` implementation now returns `io::Result` so panics are
explicitly at the `std::env` level. The panic messages have also been improved
in these situations.
Previously, if you copied a signature from a trait definition such as:
```rust
fn foo<'a>(&'a Bar) -> bool {}
```
and moved it into an `impl`, there would be an error message:
"unexpected token `'a`"
Adding to the error message that a pattern is expected should help
users to find the actual problem with using a lifetime here.
I somehow missed a word behind the numbers while going through this section, don't know what the best approach would be though since "**available** addresses" sounds good to me, too".
instead of this panic:
```
thread '<main>' panicked at 'index out of bounds: the len is 1 but the
index is 1', src/libcollections/vec.rs:1110
```
It still panics, just like `-h` does, so it should be okay in this
regard.

This commit stabilizes and deprecates library APIs whose FCP has closed in the
last cycle, specifically:
Stabilized APIs:
* `fs::canonicalize`
* `Path::{metadata, symlink_metadata, canonicalize, read_link, read_dir, exists,
is_file, is_dir}` - all moved to inherent methods from the `PathExt` trait.
* `Formatter::fill`
* `Formatter::width`
* `Formatter::precision`
* `Formatter::sign_plus`
* `Formatter::sign_minus`
* `Formatter::alternate`
* `Formatter::sign_aware_zero_pad`

* `Utf8Error::valid_up_to`
* `Iterator::{cmp, partial_cmp, eq, ne, lt, le, gt, ge}`
* `<[T]>::split_{first,last}{,_mut}`
* `Condvar::wait_timeout` - note that `wait_timeout_ms` is not yet deprecated
but will be once 1.5 is released.
* `str::{R,}MatchIndices`
* `str::{r,}match_indices`
* `char::from_u32_unchecked`
* `VecDeque::insert`
* `VecDeque::shrink_to_fit`

* `Vec::resize`
* `str::slice_mut_unchecked`
* `FileTypeExt`
* `FileTypeExt::{is_block_device, is_char_device, is_fifo, is_socket}`
* `BinaryHeap::from` - `from_vec` deprecated in favor of this
* `BinaryHeap::into_vec` - plus a `Into` impl
* `BinaryHeap::into_sorted_vec`
Deprecated APIs
