Inspired by LLVM_DEBUG, but using environment variables rather than command line options. Code can use ORC_RT_DEBUG(...) (if ORC_RT_DEBUG_TYPE is set), or ORC_RT_DEBUG_WITH_TYPE(<type>, ...) (if ORC_RT_DEBUG_TYPE is not set. E.g. in headers). Debug logging is enabled in the executor by setting the ORC_RT_DEBUG environment variable. Debug logging can be restricted by type by setting the ORC_RT_DEBUG_TYPES environment variable to a comma separated list of types, e.g. ORC_RT_DEBUG_TYPES=macho_platform,sps.
