This commit removes the std::{managed, reference} modules. The modules serve
essentially no purpose, and the only free function removed was `managed::ptr_eq`
which can be achieved by comparing references.

This removes the TotalOrd and TotalEq implementation macros, they will be added
later to the numeric modules (where the other comparison implementations live).
for `~str`/`~[]`.
Note that `~self` still remains, since I forgot to add support for
`Box<self>` before the snapshot.
How to update your code:
* Instead of `~EXPR`, you should write `box EXPR`.
* Instead of `~TYPE`, you should write `Box<Type>`.
* Instead of `~PATTERN`, you should write `box PATTERN`.

Also move prelude explanation to the prelude module.
This tries to provide a guide to what's in the standard library, organized bottom up from primitives to I/O.
This currently requires linking against a library like libquadmath (or
libgcc), because compiler-rt barely has any support for this and most
hardware does not yet have 128-bit precision floating point. For this
reason, it's currently hidden behind a feature gate.
When compiler-rt is updated to trunk, some tests can be added for
constant evaluation since there will be support for the comparison
operators.
Closes#13381
rustc: feature-gate `concat_idents!`.
concat_idents! is not as useful as it could be, due to macros only being
allowed in limited places, and hygiene, so lets feature gate it until we
make a decision about it.

A vector can reuse its allocation (and the allocations/resources of any
contained values) when cloning into an already-instantiated vector, so
we might as well do so.
The `Float` trait methods will be usable as functions via UFCS, and
we came to a consensus to remove duplicate functions like this a long
time ago.
It does still make sense to keep the duplicate functions when the trait
methods are static, unless the decision to leave out the in-scope trait
name resolution for static methods changes.
This is an implementation detail of the `f32` and `f64` modules and it
should not be public. It renames many functions and leaves out any
provided by LLVM intrinsics, so it is not a sensible binding to the C
standard library's math library and will never be a stable target.
This also removes the abuse of link_name so that this can be switched to
using automatically generated definitions in the future. This also
removes the `scalbn` binding as it is equivalent to `ldexp` when
`FLT_RADIX` is 2, which must always be true for Rust.
