Returns true if Lhs should take priority over Rhs.

This method is used by class Scheduler to select the "best" ready instruction to issue to the underlying pipelines.

Prioritize older instructions over younger instructions to minimize the pressure on the reorder buffer.

Implements llvm::mca::SchedulerStrategy.
