[llvm] FIx if-clause -Wmisleading-indentation issue.

[omtcyfz]

Summary

While bootstrapping Clang with recent gcc 6.2.0 I found a bug related to misleading indentation.

I believe, a pair of {} was forgotten, especially given the above similar piece of code:

if (!RDef || !HII->isPredicable(*RDef)) {
  Done = coalesceRegisters(RD, RegisterRef(S1));
  if (Done) {
    UpdRegs.insert(RD.Reg);
    UpdRegs.insert(S1.getReg());
  }
}

Indeed. Thanks!

lib/Target/Hexagon/HexagonExpandCondsets.cpp

if (S1.isReg()) {
           UpdRegs.insert(RD.Reg);
           UpdRegs.insert(S1.getReg());
         }
       }
     }
     if (!Done && S2.isReg()) {
       RegisterRef RS = S2;
       MachineInstr *RDef = getReachingDefForPred(RS, CI, RP.Reg, false);
-      if (!RDef || !HII->isPredicable(*RDef))
+      if (!RDef || !HII->isPredicable(*RDef)) {
         Done = coalesceRegisters(RD, RegisterRef(S2));
         if (Done) {
           UpdRegs.insert(RD.Reg);
           UpdRegs.insert(S2.getReg());
         }
       }
+    }
     Changed |= Done;
   }
   return Changed;
 }
