This will check whether conversions to and casts from void* are correct. E.g. int* -> void* -> float* will trip the sanitizer.

Calling this without any arguments makes IPO being unsupported a fatal error. I guess we can either set CMAKE_INTERPROCEDURAL_OPTIMIZATION based on if IPO is supported, or only perform this check if CMAKE_INTERPROCEDURAL_OPTIMIZATION is true.
