x86: Improve svml_s_atanhf16_core_avx512.S
Improvements are:
1. Reduce code size (-64 bytes).
2. Remove redundant move instructions.
3. Slightly improve instruction selection/scheduling where
possible.
4. Reduce rodata size ([-128, -188] bytes).
The throughput improvement is not significant as the port 0 bottleneck
is unavoidable.
