For example, what if the user gives us an input file with the section `__DATA_CONST,__got`? ld64 appears to handle this fine; it just combines the user-provided section with its own synthesized one. It also handles the case where a user input file has a `__TEXT,__mach_header` section, and treats it as distinct from its own hidden synthesized section with that name.


For a large internal binary, I confirmed that none of the input section names clashed with our synthetic section names, so I think it's pretty safe to just error out if we run into that.
