[Bug tree-optimization/30038] Call to sin(x), cos(x) should be transformed to sincos(x)

Note that for _vectorization_ of sincos we need the following:

 - a vectorized sincos implementation and vectorization support for it
   (that's the easier part).  At the moment we only can vectorize calls
   to sqrt.
 - re-order the recip pass (tree-ssa-math-opts.c) and the loop
   passes.  At the moment we generate the sincos _after_ vectorization
