94301c405c Additional traits for std::mem::ManuallyDrop 
Add pass-through implementations for all of the derivable traits. These
cannot be derived since ManuallyDrop is a union.

6276dbd953 Derive std::mem::ManuallyDrop from Clone and Copy. 
Although types that don't implement Drop can't be Copyable, this can
still be useful when ManuallyDrop is used inside a generic type. This
doesn't derive from Copy as that would require T: Copy + Clone, instead
it provides an impl of Clone for T: Clone.

02b3ae63e2 enable desugaring-sensitive error messages and use them in Try 
Maybe I should allow error messages to check the *specific* desugaring?
Thanks @huntiep for the idea!

Add align_offset intrinsic

see https://github.com/rust-lang/rfcs/pull/2043 for details and the plan towards stabilization (reexport in `core::mem` via various convenience functions)

as per @scottmcm 's [comment](https://github.com/rust-lang/rfcs/pull/2043#issuecomment-316818169), this is just the intrinsic (which is obviously unstable).

80e3f8941d Add blanket TryFrom impl when From is implemented. 
Adds `impl<T, U> TryFrom<T> for U where U: From<T>`.

Removes `impl<'a, T> TryFrom<&'a str> for T where T: FromStr` due to
overlapping impls caused by the new blanket impl. This removal is to
be discussed further on the tracking issue for TryFrom.

Generate builtin impls for `Clone`

This fixes a long-standing ICE and limitation where some builtin types implement `Copy` but not `Clone` (whereas `Clone` is a super trait of `Copy`).

However, this PR has a few side-effects:
* `Clone` is now marked as a lang item.
* `[T; N]` is now `Clone` if `T: Clone` (currently, only if `T: Copy` and for `N <= 32`).
* `fn foo<'a>() where &'a mut (): Clone { }` won't compile anymore because of how bounds for builtin traits are handled (e.g. same thing currently if you replace `Clone` by `Copy` in this example). Of course this function is unusable anyway, an error would pop as soon as it is called.

Hence, I'm wondering wether this PR would need an RFC...
Also, cc-ing @nikomatsakis, @arielb1.
