We can now use raw pointer casts `*const [T] as *const T` and `*const str as *const u8` instead of .repr() for getting the pointer out of a slice.
These types were already `!Sync`, but this improves error messages when they are used in contexts that require `Sync`, aligning them with conventions used with `Rc`, among others.
Was getting error: ``` running: "sh" "/home/flubba86/rust/src/libstd/../libbacktrace/configure" "--with-pic" "--disable-multilib" "--disable-shared" "--disable-host-shared" "--host=asmjs-unknown-emscripten" "--build=x86_64-unknown-linux-gnu" ... Invalid configuration `asmjs-unknown-emscripten': system `emscripten' not recognized ``` Undo change to libbacktrace configure script. Modify libstd build.rs to not build libbacktrace in the case of targeting emscripten.

…n_fix, r=alexcrichton Was getting error: ``` running: "sh" "/home/flubba86/rust/src/libstd/../libbacktrace/configure" "--with-pic" "--disable-multilib" "--disable-shared" "--disable-host-shared" "--host=asmjs-unknown-emscripten" "--build=x86_64-unknown-linux-gnu" ... Invalid configuration `asmjs-unknown-emscripten': system `emscripten' not recognized ``` This commit adds the emscripten target to the libbacktrace configure script so it is no longer unrecognized.
…ndirection, r=bluss This allows a bit more flexibility in how to use it, see the included test case.
Use raw pointer casts for slice, str's .as_ptr() We can now use raw pointer casts `*const [T] as *const T` and `*const str as *const u8` instead of .repr() for getting the pointer out of a slice.
