LGTM, but let's wait for one day or two to see others' opinions.



================
Comment at: llvm/lib/Target/X86/X86PreTileConfig.cpp:227
 
-static void addTileCFGUse(MachineFunction &MF, Register CFG) {
-  for (MachineBasicBlock &MBB : MF) {
+void X86PreTileConfig::reloadTileConfig(int FI) {
+  SmallSet<MachineInstr *, 8> MIVisited;
----------------
The code here looks correct but not optimized to me. But I think we can land it first and refine it later.
