[COMMITTED] math: Update tanh from CORE-MATH (revision bb39e4fa)

The bug only exists in the non-FMA-contracted compilation of that
branch. On x86_64 it can be triggered with:
GLIBC_TUNABLES=glibc.cpu.hwcaps=-AVX2 math/test-double-tanh
Or by building without ifunc support.
Checked on aarch64-linux-gnu and x86_64-linux-gnu with
--disable-multi-arch.
