The last (big) missing piece to get "math" working in OpenMP target
regions (that I know of) was complex math functions, e.g.,
`std::sin(std::complex<double>)`. With this patch we overload the system
template functions for these operations with versions that have been
distilled from `libcxx/include/complex`. We use the same

  `omp begin/end declare variant`

mechanism we use for other math functions before, except that we this
time overload templates (via D85735 <https://reviews.llvm.org/D85735>).
