Optimize sin/cos
GCC/Clang can optimize to calculate `sin(x)` and `cos(x)` at once,
when the both are closely called on the same argument.
Similar optimization is possible for `__sinpi(x)` and `__cospi(x)`
if available, which calculate arguments in radian, i.e.
`sin(x*M_PI)` and `cos(x*M_PI)` respectively.
