Summary: For lldb-server, it is sufficient to parse only the native object file format for its target OS (no other file can be loaded into a running process). This moves the object file initialization code into specific initializer classes: lldb-test and liblldb get all object files; lldb-server gets only one of them. For this to work, I've needed to create a special SystemInitializer for use in lldb-server, instead of it calling directly into the common one. This reduces the size of lldb-server by about 2%, which is not earth-shattering, but it's an easy win, and it helps.
