This change enables integrating orc::LLJIT with the ORCv2 platforms (MachOPlatform and ELFNixPlatform) and the compiler-rt orc runtime. Changes include: - Adding SPS wrapper functions for the orc runtime's dlfcn emulation functions, allowing initialization and deinitialization to be invoked by LLJIT. - Changing the LLJIT code generation default to add UseInitArray so that .init_array constructors are generated for ELF platforms. - Integrating the ORCv2 Platforms into lli, and adding a PlatformSupport implementation to the LLJIT instance used by lli which implements initialization and deinitialization by calling the new wrapper functions in the runtime.
