ok, I was just basing this off of existing tests.  But I see that recently there has been support for targets in the REQUIRES statements.  I'll change these for both the Windows and Linux tests.  Also, for the .cl version of the test, I'm not sure if it would change much in how we create and use the ToolChains in the Driver.  But, better to be safe.  I'll add .cl versions for both tests.
