f7cf1f62 - [CodeGen][MISched] dumpSched direction depends on field in DAG.

[CodeGen][MISched] dumpSched direction depends on field in DAG. This is a precommit to supporting post reg-alloc bottom up scheduling. We'd like to have post-ra scheduling direction that can be different from pre-ra direction. The current dumpSchedule function is changed in this patch to support the fact that the post-ra and pre-ra directions will depend on different command line options.
