Georgii Rymar 98a4289810 [llvm-readobj] - For SHT_REL relocations, don't display an addend. 
This is https://bugs.llvm.org/show_bug.cgi?id=44257.

In LLVM style we always print `0` as addend when dumping
SHT_REL relocations. It is confusing, this patch stops
printing it as the first comment on the bug page suggests.

Fangrui Song f3a3b93f54 [ELF] -r: fix R_*_NONE to section symbols on Elf*_Rel targets 
On Elf*_Rel targets, for a relocation to a section symbol, an R_ABS is
added which will be used by relocateOne() to compute the implicit
addend.

Addends of R_*_NONE should be ignored, so don't emit an R_ABS.

This fixes crashes on X86 and ARM because their relocateOne() do not
handle R_*_NONE.

Fangrui Song ef9b8e03fd [ELF][test] Reorganize some R_*_NONE tests 
Change R_{386,AARCH64}_NONE yaml2obj tests/icf10.test to use assembly

Add relocation-none-{arm,x86_64}.s.
  Check the referenced section survives under --gc-sections.
  Check -r copies R_X86_64_NONE R_AARCH64_NONE. (Elf*_Rel arches currently have a bug)
  Delete the dtrace tests as they are covered by the R_X86_64_NONE test.
