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
