Sebastian Pop 5c87daf2c8 add TableGen support to create relationship maps between instructions 
Relationship maps are represented as InstrMapping records which are parsed by
TableGen and the information is used to construct mapping tables to represent
appropriate relations between instructions. These tables are emitted into
XXXGenInstrInfo.inc file along with the functions to query them.

Jakob Stoklund Olesen e6aed139f0 Write llvm-tblgen backends as functions instead of sub-classes. 
The TableGenBackend base class doesn't do much, and will be removed
completely soon.
