Fangrui Song f5b42eaadb [ELF] -r --compress-debug-sections: update implicit addends for .rel.debug_* referencing STT_SECTION symbols (#66804) 
https://reviews.llvm.org/D48929 updated addends for non-SHF_ALLOC sections
relocated by REL for -r links, but the patch did not update the addends when
--compress-debug-sections={zlib,zstd} is used (#66738).

https://reviews.llvm.org/D116946 handled tombstone values in debug
sections in relocatable links. As a side effect, both
relocateNonAllocForRelocatable (using `sec->relocations`) and
relocatenonNonAlloc (using raw REL/RELA) may run.

Actually, we can adjust the condition in relocatenonAlloc to completely replace
relocateNonAllocForRelocatable. This patch implements this idea and fixes #66738.

As relocateNonAlloc processes the raw relocations like copyRelocations() does,
the condition `if (config->relocatable && type != target.noneRel)` in `copyRelocations`
(commit 08d6a3f133, modified by https://reviews.llvm.org/D62052)
can be made specific to SHF_ALLOC sections.

As a side effect, we can now report diagnostics for PC-relative relocations for
-r. This is a less useful diagnostic that is not worth too much code. As
https://github.com/ClangBuiltLinux/linux/issues/1937 has violations, just
suppress the warning for -r. Tested by commit 561b98f9e0.
