  1. librustc: add rint and nearbyint intrinsics to go with ceil and trunc… 

    … from LLVM 3.3.

  2. librustc: use LLVM intrinsics for several floating point operations. 

    Achieves up to 5x speed up! However, the intrinsics seem to do bad
things to the stack, especially sin, cos and exp (rust-lang#5686 has
discussion).

Also, add f{32,64,loat}::powi, and reorganise the delegation code so
that functions have the #[inline(always)] annotation, and reduce the
repetition of delegate!(..).
