Tue Ly 92bc7f5428 [libc][math] Update range reduction step for log2f and improve its performance. 
Simplify the range reduction steps by choosing the reduction constants
carefully so that the reduced arguments v = r*m_x - 1 and v^2 are exact in double
precision, even without FMA instructions, and -2^-8 <= v < 2^-7.
