Postpone this patch. We need to wait for the resolution to "what fields are used to differentiate two sections"

Currently it is (section_name,group_name,unique_id).
Adding linked_to_sym seems reasonable (D74006 <https://reviews.llvm.org/D74006>; it is hjl's GNU as patch will do). hjl and I favor it.
One opinion (@bd1976llvm's) is that sh_entsize should also be taken into account.
If we eventually add sh_type/sh_flags to the differentiator, then this patch will not be needed.

There are some discussions on D74006 <https://reviews.llvm.org/D74006> and https://bugs.llvm.org/show_bug.cgi?id=44775
