06c5e7f383 Implement exp_m1 and ln_1p as methods for Float 
Both expm1 and ln1p have been renamed to exp_m1 and ln_1p in order to be consistent with the underscore usage elsewhere.

The exp_m1 method is used for increased accuracy when doing floating point calculations, so this has been moved from the more general 'Exponential' trait into 'Float'.

500078e147 Revert "Merge Exponential and Hyperbolic traits" 
After discussions on IRC and #4819, we have decided to revert this change. This is due to the traits expressing different ideas and because hyperbolic functions are not trivially implementable from exponential functions for floating-point types.

d3f494f5c3 Merge Exponential and Hyperbolic traits 
The Hyperbolic Functions are trivially implemented in terms of `exp`, so it's  simpler to group them the Exponential trait. In the future these would have default implementations.

6cc7107aa6 Add Orderable trait 
This is a temporary trait until we have default methods. We don't want to encumber all implementors of Ord by requiring them to implement these functions, but at the same time we want to be able to take advantage of the speed of the specific numeric functions (like the `fmin` and `fmax` intrinsics).

d9c54f8387 librustc: use LLVM intrinsics for several floating point operations. 
Achieves at least 5x speed up for some functions!

Also, reorganise the delegation code so that the delegated function wrappers
have the #[inline(always)] annotation, and reduce the repetition of
delegate!(..).

675bdcf341 Created libcore/private/intrinsics.rs, which aims to contain every 
rustc intrinsic. Several files in libcore have been changed to use
these intrinsics.
As of yet, none of the intrinsics are documented.
