These symbols are somewhat interesting in that they create non-existing
segments, which as far as I know is the only way to create segments
that don't contain any sections.

Final part of part of PR50760. Like D106629 <https://reviews.llvm.org/D106629>, but for segments instead
of sections. I'm not aware of anything that needs this in practice.
