* Move 'force-unstable-if-unmarked' to the bootstrapping chapter
* Document how to stabilize a library feature
Note that features can't be stabilized until they go through FCP and
that FCP happens on the tracking issue, not the PR.
* Fix wrong glob
By default `**` behaves the same as two `*` side by side, i.e. it only
globs file paths, not directories. `shopt -s globstar` needs to be set
for it to mean a directory. I didn't notice this before now because
`globstar` is set by default in interactive mode, but not otherwise.
`download-ci-llvm` is available and enabled by default for all tier 1
platforms, so there is no need to change it. Using system LLVM over CI
llvm is still supported, but is not recommended. Building LLVM from
source is still supported.
This also notes that you need to explicitly disable downloading LLVM
when updating the submodule.
Document the newly added `x` binary that wraps `x.py`, which can be
installed system-wide, and can be run from any subdirectory of a rust
repo checkout.
This makes the compiler faster to running without sacrificing too much
performance. It still shows logging so contributors aren't confused by
`debug!` doing nothing.
This is a companion to [this PR](https://github.com/rust-lang/rust/pull/76356), which deals with including functionality for automatically running `tidy --bless` on each commit.

* Explain stages in terms of the compiler currently running
- Address some confusing points
+ stage N+1 -> stage N artifacts
+ Use more likely examples of an ABI break
+ stage N -> stage N compiler
- Mention why rustc occasionally uses `cfg(bootstrap)`
- Note that stage1 is built using two different versions
- Add lots of examples
+ `test src/test/ui` and `test compiler/rustc` run different compilers 😢
+ Separate examples of what to do from examples of what not to do
- 'ship stage 1 artifacts' -> 'ship stage 2 compiler'
This is hopefully less confusing.
* build -> x.py build
* Add section on build artifacts
* Improve wording
