Summary: We call the global constructors by function pointer. For whatever reason the NVPTX architecture relies very specifically on the arguments to the function pointer invocation matching what the function is implemented as. This is problematic as most of these constructors are generated with no arguments. This patch removes the extended arguments that GNU and LLVM use for the constructors optionally so that it can support the common case.
