e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

Remove critical edge breaking.  It won't be necessary as long as we are very careful when inserting copies.

Remove ugly and horrible code.  It's not necessary for correctness, and can be added back later if it causes code quality issues.
