This revision is now accepted and ready to land.

This seems reasonable to me, unless @RKSimon has concerns.



================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineVectorOps.cpp:1937-1939
+    SmallVector<Constant *, 16> ScaledMaskC;
+    for (unsigned i = 0; i != VWidth; ++i)
+      ScaledMaskC.push_back(Builder.getInt32(ScaledMask[i]));
----------------
Same comment about reserve+range-based-for, although i hope that will get obsoleted by D72467?
