Sometimes ELF files have segments in them which are marked as loadable, but which actually have zero size in memory. When setting up a memory image we should drop those to avoid confusing other code which tries to find the footprint of a memory image. No part of these segments, including their starting address or ending address, need to actually land on top of memory since they don't actually contain any data.
