During PHDR creation, the case where an output section does not require a PT_LOAD header but still occupies memory in the current VMA region was not handled. If such an output section interleaves two output sections that have the same VMA and LMA regions set, we would previously re-use the existing PT_LOAD header for the second output section. However, since the memory region is not contiguous, we need to start a new PT_LOAD segment. This fixes https://bugs.llvm.org/show_bug.cgi?id=50558 Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D103815
