Hongbin Zheng d1b7b2efba [SimplifyIndVar] Constant fold IV users ...

This patch tries to transform cases like:

for (unsigned i = 0; i < N; i += 2) {
  bool c0 = (i & 0x1) == 0;
  bool c1 = ((i + 1) & 0x1) == 1;
}
To

for (unsigned i = 0; i < N; i += 2) {
  bool c0 = true;
  bool c1 = true;
}

This commit also update test/Transforms/IndVarSimplify/replace-srem-by-urem.ll to prevent constant folding.
