- Adapt MachineBasicBlock::getName() to have the same behavior as the IR
BasicBlock (Value::getName()).
- Add it to lib/CodeGen/CodeGen.cpp::initializeCodeGen so that it is linked in
the CodeGen library.
- MachineRegionInfoPass's name conflicts with RegionInfoPass's name ("region").
- MachineRegionInfo should depend on MachineDominatorTree,
MachinePostDominatorTree and MachineDominanceFrontier instead of their
respective IR versions.
- Since there were no tests for this, add a X86 MIR test.
