Add sinf/cosf/sincosf benchmark

Similar to expf/exp2f, this patch add two benchmarks for sinf, cosf, and
sincosf: one which measures thoughput as default and one which measures
latency.

The input in 512 random value divided in 8 ranges:

  1. 0.0 <= x < 0.1
  2. 0.1 <= x < 0.7
  3. 0.7 <= x < 3.1
  4. -3.1 <= x < 3.1
  5. 3.3 <= x < 33.3
  6. 100.0 <= x < 1000.0
  7. 1e6 <= x < 1e32
  8. 1e32 < x < FLT_MAX

Test: ran 32-bit and 64-bit x86 tests on host
