================
Comment at: llvm/unittests/CodeGen/GlobalISel/GISelMITest.h:111
+    liveins: $x0, $x1, $x2, $x4
+
     %0(s64) = COPY $x0
----------------
In case someone wonders, this change is required to have MIRString with basic blocks that have variables that are live out, otherwise the machine verifier will complain that some variables are not live out of the predecessors when use in a phi.
(Basically we need the tracksRegLiveness property and when we set it, we need to mark as live ins all phys regs that are used across all the GISel tests.)
