math: Add tan implementation
Uses the algorithm:
tan(x) = sin(x) / sqrt(1-sin^2(x))
An alternative is:
tan(x) = sin(x) / cos(x)
Which produces more verbose bitcode and longer assembly.
Either way, the generated bitcode seems pretty nasty and a more optimized
but still precise-enough solution is welcome.
