  Changed paths:
    M llvm/include/llvm/CodeGen/MachineScheduler.h
    M llvm/lib/CodeGen/MachineScheduler.cpp
    A llvm/test/CodeGen/AArch64/dump-schedule-trace.mir

  Log Message:
  [MISched] Dump the execution trace of the schedule.

The traces are printed only for bottom-up and top-down scheduling
because the values of TopReadyCycle and BottomReadyCycle are
inconsistent when obtained via bidirectional scheduling (see
`BIDIRECTIONAL` checks in the test).

Differential Revision: https://reviews.llvm.org/D142529
