Sorting an array doesn’t compile when targeting nvvm

[sebcrozet]

The following piece of code:

let mut foo = [1usize, 2];
foo.sort_unstable();

fails to compile with the error:

error: internal compiler error: C:\Users\devel\.cargo\registry\src\github.com-1ecc6299db9ec823\rustc_codegen_nvvm-0.1.0\src\context.rs:373:32: unknown intrinsic 'llvm.bswap.i64'

I originally triggered this error while attempting to use the sorted variant of the SVD decomposition in nalgebra.

Weird, looks like somewhere along the line i deleted bswap from ctx_intrinsics, which is wrong because nvvm supports it

Should be fixed in cg_nvvm 0.1.1
