  [OpenMP] Make complex soft-float functions on the GPU weak definitions

To avoid linkage errors we have to ensure the linkage allows multiple
definitions of these compiler inserted functions. Since they are on the
cold path of complex computations, we want to avoid `inline`. Instead,
we opt for `weak` and `noinline` for now.
