This PR will fix https://github.com/apache/tvm/issues/19592. LayerNorm could produce NaN on large-value, small-variance inputs due to catastrophic cancellation in var = E[x^2] - E[x]^2. Switch to a numerically stable two-pass formulation: - pass1 computes mean via sum(x) / N - pass2 computes variance via sum((x - mean)^2) / N -- This is an automated message from the Apache Git Service.
