Outside of clang/test/Driver, tests should use %clang_cc1 to run the frontend directly instead of via the driver. This will require some minor adjustment to the command-line options, for example -target becomes -triple and -g generally becomes -debug-info-kind=limited.

Also, the x86_64 triple will do the wrong thing on a Windows host. You probably want %itanium_abi_triple there.
