x86: Improve svml_s_atanhf8_core_avx2.S
Improvements are: 1. Reduce code size (-60 bytes). 2. Remove redundant move instructions. 3. Slightly improve instruction selection/scheduling where possible. 4. Prefer registers which get short instruction encoding. 5. Shrink rodata usage (-32 bytes). The throughput improvement is not that significant (3-5%) as the port 0 bottleneck is unavoidable.
