This PR uses fast_exp to convert power op to fast but approximate counterpart. When y is not an integer, fast_exp(log(x) * y) is much faster than topi.power(x, y). However, if y is not a constant, fast_exp(log(x) * y) will get a wrong anwser when x < 0 and y is an integer. To fix this problem, this PR uses power(x, y) = exp(log(abs(x)) * y) * (log((x / abs(x) - 1) * (ceil(y) - floor(y)) + 1) + (x / abs(x) - 1) * (y % 2) + 1). -- This is an automated message from the Apache Git Service.
