On some architectures, vector types may have a different ABI when relevant target features are enabled. As discussed in https://github.com/rust-lang/lang-team/issues/235, this turns out to very easily lead to unsound code. This commit makes it an error to declare or call functions using those vector types in a context in which the corresponding target features are disabled, if using an ABI for which the difference is relevant.
