We had been using clang/llvm 12 and when trying out 14 I started
getting test failures with OptiX compliaining about duplicate
symbols. They all seemed to be the things we declared as
OSL_CONSTANT_DATA. It looks like there's a difference in llvm 12 vs 14
in how the generated PTX marks its symbol visibility.
The solution (thanks to a clever suggestion by Alex Conty) was just to
enclose those declarations in anonymous namespaces. Works like a
charm!
