  -----------
  [DAGCombiner] Teach MatchContextClass classes to use TargetLowering::isOperationLegalOrCustom().

Some of TargetLowering functions needed opcodes are often used in DAGCombiner.
The patch make those MatchContextClass classes have TargetLowering members and
pass specific opcodes for those TargetLowering functions.
