With the help of @lhames, This pull request introduces the dlupdate function in the ORC runtime. dlupdate enables incremental execution of new initializers introduced in the REPL environment. Unlike traditional dlopen, which manages initializers, code mapping, and library reference counts, dlupdate focuses exclusively on running new initializers.
