LGTM. Since nikic was the primary review give him a few days to potentially add more feedback before pushing.



================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp:3494
+    // When c == 0, this simplifies to
+    // - usub.sat(a, b) == 0 ->  a <= b
+    // - usub.sat(a, b) != 0 -> a > b
----------------
nit: extra space before "a <= b" compared to below.
