The -alias option can be used to define aliases within a JITDylib. The immediate motivation is to simplify testing of ORC runtime functions using existing testcases (e.g. by aliasing dlfcn functions to their ORC-runtime counterparts, like -alias dlopen=__orc_rt_macho_dlopen). The option is likely to be useful for testing in general. The -define-abs option is shortened to -abs for consistency with -alias.
