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.
