i686: Use generic cosf implementation for SSE2 version
Performance seems to be similar (gcc 11.2.1 on a Ryzen 9 5900X):
* s_cosf-sse2.S:
"cosf": {
"workload-random": {
"duration": 3.74987e+09,
"iterations": 9.616e+07,
"reciprocal-throughput": 15.8141,
"latency": 62.1782,
"max-throughput": 6.32346e+07,
"min-throughput": 1.60828e+07
}
}
* generic s_cosf.c:
"cosf": {
"workload-random": {
"duration": 3.87298e+09,
"iterations": 1.00968e+08,
"reciprocal-throughput": 18.3448,
"latency": 58.3722,
"max-throughput": 5.45113e+07,
"min-throughput": 1.71314e+07
}
}
Checked on i686-linux-gnu.
