Add `as_mut` methods to the `std::cell` structs
This is safe since the borrow checking ensures that we have the only
mutable reference to the struct, thus we can safely borrow its interior.

Tracking issue is #33444.
The definition of this value recently changed slightly. It no
longer corresponds directly to the target triple.
Also shuffled things around to make the order of cfg descriptions more
logical and added text related them to the target triple.

We will no longer use `ccache` in the makefiles for our local dependencies like
miniz, but they're so small anyway it doesn't really matter.

Add more aliases for Unicode confusable chars
Building upon #29837, this PR:
* added aliases for space characters,
* distinguished square brackets from parens, and
* added common CJK punctuation characters as aliases.
This will especially help CJK users who may have forgotten to switch off IME when coding.
If the `-f` option isn't given, GNU tar will use environment variable
`TAPE` first, and next use the compiled-in default, which isn't
necessary `stdout` (it is the tape device `/dev/rst0` under OpenBSD for
example).

mk: Pass CFLAGS for target, not host
This changes the CFLAGS and related variables passed to compiletest to be passed
for the target, not the host, so we can correctly test 32-bit cross compiles on
64-bit host machines.
Hopefuly fixes#33379
Right now they're `gnueabihf` and `gnueabi`, but when adding new platforms like
musl on ARM it's unfortunate to have to test for all three (`musl`, `musleabi`,
and `musleabihf`). This PR switches everything currently to `gnu`, and the new
musl targets can also use `musl` when they land.
Closes#33244
Clients can now use the rustdoc syntax highlighter to classify tokens, then use that info to put together there own HTML (or whatever), rather than just having static HTML output.
This commit expands the bootstrap build system's `README.md` as well as ensuring
that all API documentation is present and up-to-date. Additionally a new
`config.toml.example` file is checked in with commented out versions of all
possible configuration values.

This requirement appears to be missing from RFC1214, but is clearly
necessary for translation. The last field of a tuple/enum remains in
a state of limbo, compiling but causing an ICE when it is used - we
should eventually fix that somehow.
this is a [breaking-change] - a soundness fix - and requires a
crater run.
Put a constraint type on every ADT def, such that the ADT def is sized iff the constraint
type is, and use that in selection. This ignores types that are obviously sized.
This improves typeck performance by ~15%.
rustdoc: HTML-escape Rust code (from constants)
Especially in cases like the one in the test file, this can blow up the rendering big time if string constants in the code contain HTML.
But also other constants can contain special chars (e.g. `&` as an operator in constant expressions).
rustdoc: fix inserting source code spans for constant values
This will go wrong when the constants partially result from macro expansion.
Instead, use the expressions and pretty-print them as Rust code.
Fixes: #33302
