[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.
