Andrew Trick 47ff14b091 Convert -enable-sched-cycles and -enable-sched-hazard to -disable 
flags. They are still not enable in this revision.

Added TargetInstrInfo::isZeroCost() to fix a fundamental problem with
the scheduler's model of operand latency in the selection DAG.

Generalized unit tests to work with sched-cycles.
