[SelectionDAG] Make fast and linearize visible by clang -pre-RA-sched ScheduleDAGFast.cpp is compiled to object file, but the ScheduleDAGFast object file isn't linked into clang executable file as no symbol is referred by outside. Add calling to createXxx of ScheduleDAGFast.cpp, then the ScheduleDAGFast object file will be linked into clang executable file. The static RegisterScheduler will register scheduler fast and linearize at clang boot time. Reviewed By: pengfei Differential Revision: https://reviews.llvm.org/D101601
