Mikhail Maltsev c4658abe60 [libcxx] Improve accuracy of complex asinh and acosh ... Summary: Currently std::asinh and std::acosh use std::pow to compute x^2. This results in a significant error when computing e.g. asinh(i) or acosh(-1). This patch expresses x^2 directly via x.real() and x.imag(), like it is done in libstdc++/glibc, and adds tests that checks the accuracy.
