dd862356 - AsmPrinter: Remove ELF's special lowerRelativeReference for unnamed_addr function

AsmPrinter: Remove ELF's special lowerRelativeReference for unnamed_addr function https://reviews.llvm.org/D17938 introduced lowerRelativeReference to give ConstantExpr sub (A-B) special semantics in ELF: when `A` is an `unnamed_addr` function, create a PLT-generating relocation. This was intended for C++ relative vtables, but C++ relative vtable ended up using DSOLocalEquivalent (lowerDSOLocalEquivalent). This special treatment of `unnamed_addr` seems unusual. Let's remove it. Only COFF needs an overload to generate a @IMGREL32 relocation specifier (llvm/test/MC/COFF/cross-section-relative.ll). Pull Request: https://github.com/llvm/llvm-project/pull/132684
