7522 - bring back a few tests in .subx files
Even though baremetal has tests in SubX, they can only run in Mu programs since the test harness is currently in a Mu layer. Baremetal isn't really intended for running SubX programs at the moment. Is this a step down the slippery slope towards C compilers that I complained about in http://akkartik.name/akkartik-convivial-20200607.pdf?
