Update target_feature syntax (#283)
This commit updates to the latest nightly's syntax where `#[target_feature =
"+foo"]` is now deprecated in favor of `#[target_feature(enable = "foo")]`.
Additionally `#[target_feature]` can only be applied to `unsafe` functions for
now.

Along the way this removes a few exampels that were just left around and also
disables the `fxsr` modules as that target feature will need to land in upstream
rust-lang/rust first as it's currently unknown to the compiler.
