This commit adds the liveins and successors properties to machine basic blocks in some of the MIR tests to ensure that the tests will pass when the MIR parser will run the machine verifier after initializing a machine function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@243124 91177308-0d34-0410-b5e6-96231b3b80d8
