* Added instruction property hasCtrlDep for those which r/w control-flow

  chains.
* Added DAG node property SDNPHasChain for nodes which r/w control-flow
  chains.
* Renamed SDTVT to SDTOther.
* Added several new SDTypeProfiles for BR, BRCOND, RET, and WRITEPORT.
* Added SDNode definitions for BR, BRCOND, RET, and WRITEPORT.
