Because of -ffunction-sections (and maybe other use cases I'm not aware of?) it can occur that we need more than 0xfeff sections but ELF dosn't support that many sections. To solve this problem SHN_XINDEX exists and with it come a whole host of changes for section indexes everywhere. This change adds support for those cases which should allow llvm-objcopy to copy binaries that have an arbitrary number of sections.
