  -----------
  [CUDA] pass -fno-threadsafe-statics to GPU sub-compilations. (#117074)

We do not have support for the threadsafe statics on the GPU side.

However, we do sometimes end up with empty local static initializers,
and those happen to trigger calls to `__cxa_guard*`, which breaks
compilation.
