that control, individually, all of the disparate things it was controlling. At the same time move a FIXME in the Hexagon port to a new subtarget function that will enable a user of the machine scheduler to avoid using the source scheduler for pre-RA-scheduling. The FIXME would have this removed, but involves either testcase changes or adding -pre-RA-sched=source to a few testcases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231980 91177308-0d34-0410-b5e6-96231b3b80d8
