x86: Optimize svml_s_tanhf8_core_avx2.S
Optimizations are:
1. Reduce code size (-81 bytes).
2. Remove redundant move instructions.
3. Slightly improve instruction selection/scheduling where
possible.
4. Prefer registers which get short instruction encoding.
5. Reduce rodata size (-32 bytes).
Result is roughly a 17-18% speedup:
Function, New Time, Old Time, New / Old
_ZGVdN8v_tanhf, 1.977, 2.402, 0.823
