2020-10-29math: add scalar erff.Pierre Blanchard
In round-to-nearest mode the maximum error is 1.09 ULP. Compared to glibc-2.28 erff: throughput is about 2.2x better, latency is about 1.5x better on some AArch64 cores (on random input in [-4,4]). There are further optimization and quality improvement opportunities.
