Boolean values and small aggregates have a different type in args/allocas than
in SSA values but the intrinsics for volatile and atomic ops were
missing the necessary casts to handle that.
Fixes#23550
This commit removes the `IndexMut` impls on `HashMap` and `BTreeMap`, in
order to future-proof the API against the eventual inclusion of an
`IndexSet` trait.
Ideally, we would eventually be able to support:
```rust
map[owned_key] = val;
map[borrowed_key].mutating_method(arguments);
&mut map[borrowed_key];
```
but to keep the design space as unconstrained as possible, we do not
currently want to support `IndexMut`, in case some other strategy will
eventually be needed.
Code currently using mutating index notation can use `get_mut` instead.

After this patch code like `let ref a = *"abcdef"` doesn't cause ICE anymore.
Required for #23121
There are still places in rustc_trans where pointers are always assumed to be thin. In particular, #19064 is not resolved by this patch.

This commit removes the reexports of `old_io` traits as well as `old_path` types
and traits from the prelude. This functionality is now all deprecated and needs
to be removed to make way for other functionality like `Seek` in the `std::io`
module (currently reexported as `NewSeek` in the io prelude).

This is temporarily rebased on #23245 as it would otherwise conflict, the last commit is the only one relevant to this PR though.

When investigating #22518, this chapter is really the only part that has `rand`, and the rest still works without it. We should have some examples like this, but for now, it's more important to be right than perfect.
As @alexcrichton says, this was really a libgreen thing, and isn't
relevant now.

`uppercase` and `lowercase` are currently named `to_uppercase` and `to_lowercase`. Also adds a link to the `char` type documentation which has much more detail on these iterators.
These two borrowing examples were confusing/misleading. This changes it
to more clearly show how you _can_ borrow a box, and also uses & instead
of &*.
We don't use 'task' anymore, these are now threads.
Because this changes the name of a compiler option, this is

I think this is small enough to not need an RFC, nor a period of accepting both. If we want to take both for a while, I can change the patch.
The IP and socket address types all had `FromStr` implemented but the
implementations were not marked stable, nor was the error type returned ready to
be properly stabilized.
This commit marks the implementations of `FromStr` as stable and also renamed
the `ParseError` structure to `AddrParseError`. The error is now also an opaque
structure that cannot be constructed outside the standard library.
