There's a fair number of attributes that have to be whitelisted since
they're either looked for by rustdoc, in trans, or as needed. These can
be cleaned up in the future.
Some functions implemented for the Ascii struct have the same functionality as other functions implemented for the normal chars. For consistency, I think they should have the same name, so I renamed the functions in Ascii to match the names in the Char trait.
* Renamed `to_lower` to `to_lowercase`
* Renamed `to_upper` to `to_uppercase`
* Renamed `is_alpha` to `is_alphabetic`
* Renamed `is_alnum` to `is_alphanumeric`
* Renamed `is_lower` to `is_lowercase`
* Renamed `is_upper` to `is_uppercase`

On some systems (iOS for example) mutex is represented by opaque data structure which doesn't play well with simple data copy. Therefore mutex should be initialized from magic static value and filled by OS only when it landed RC.
Initially written for iOS but since landing iOS support might require quite a lot of time I think it is better to split parts which aren't directly related to iOS and merge them in

* All of the *_val functions have gone from #[unstable] to #[stable]
* The overwrite and zeroed functions have gone from #[unstable] to #[stable]
* The uninit function is now deprecated, replaced by its stable counterpart,
uninitialized

We can now mark arguments and returns as `nonnull` in LLVM. It's still somewhat limited by the fact that LLVM loses this information after inlining but it might help in certain cases.
All of these features have been obsolete since February 2014, where most have
been obsolete since 2013. There shouldn't be any more need to keep around the
parser hacks after this length of time.
It can be easy to accidentally bloat the size of an enum by making one variant
larger than the others. When this happens, it usually goes unnoticed. This
commit adds a lint that can warn when the largest variant in an enum is more
than 3 times larger than the second-largest variant. This requires a little
bit of rejiggering, because size information is only available in trans, but
lint levels are only available in the lint context.
It is allow by default because it's pretty noisy, and isn't really *that*
undesirable.
Closes#10362
