Hide the visibility of the C++ operators by default.
Hide the visibility of the C++ operators by default.

Currently the export of the C++ operators can cause issues when interoping with
native code on (at least) OSX, since it will hook the delete from native libraries.
This should be fixed long term by #247 when proper library exports are figured out
but for now we can just hide these on llvm.

Fixes #943
