Memprof: optimize random sampling (#9466)

Instead of using the stdlib logf function for computing logarithms, we
use a faster polynomial-based approximation.

We use the xoshiro PRNG instead of the Mersenne Twister.  xoshiro is
simpler and faster.

We generate samples by batches so that compilers can vectorize the
generation loops using SIMD instructions when possible.
