LLVM is moving towards the `target=<target triple RE>` syntax in `XFAIL: ` etc., and I'll need the same in a subsequent patch. This patch adds the necessary infrastructure. Tested on `sparc-sun-solaris2.11`, `sparcv9-sun-solaris2.11`, `sparc-unknown-linux-gnu`, `sparc64-unknown-linux-gnu`, `i386-pc-solaris2.11`, `amd64-pc-solaris2.11`, `i686-pc-linux-gnu`, and `x86_64-pc-linux-gnu`.
