Fangrui Song ae73091f30 [ELF] -r: don't crash when a non-SHF_LINK_ORDER orphan is added before a SHF_LINK_ORDER orphan
Fixes https://github.com/ClangBuiltLinux/linux/issues/1186

If a non-SHF_LINK_ORDER orphan is added first, `firstIsec->flags & SHF_LINK_ORDER`
will be zero and we currently assert when calling `getLinkOrderDep`.

# REQUIRES: x86
## In a relocatable link, don't combine SHF_LINK_ORDER and non-SHF_LINK_ORDER
## like we don't combine SHF_LINK_ORDER with different linked-to sections
## (see linkerscript/linkorder-linked-to.s).
## Test we support adding a non-SHF_LINK_ORDER section as an orphan first.
