i686: Use generic sincosf implementation for SSE2 version
The generic implementation shows slight better performance
(gcc 11.2.1 on a Ryzen 9 5900X):
* s_sincosf-sse2.S:
"sincosf": {
"workload-random": {
"duration": 3.89961e+09,
"iterations": 9.5472e+07,
"reciprocal-throughput": 40.8429,
"latency": 40.8483,
"max-throughput": 2.4484e+07,
"min-throughput": 2.44808e+07
}
}
* generic s_cossinf.c:
"sincosf": {
"workload-random": {
"duration": 3.71953e+09,
"iterations": 1.48512e+08,
"reciprocal-throughput": 25.0515,
"latency": 25.0391,
"max-throughput": 3.99177e+07,
"min-throughput": 3.99375e+07
}
}
Checked on i686-linux-gnu.
