[LLD] [COFF] Fix reporting duplicate errors for absolute symbols Previously this caused crashes in the reportDuplicate method. A DefinedAbsolute doesn't have any InputFile attached to it, so we can't report the file for the original symbol. We could add an InputFile argument to SymbolTable::addAbsolute only for the sake of error reporting, but even then it'd be assymetrical, only pointing out the file containing the new conflicting definition, not the original one. Differential Revision: https://reviews.llvm.org/D71679

// RUN: llvm-mc -triple x86_64-windows-msvc -filetype obj -o %t.obj %s
[LLD] [COFF] Don't error out on duplicate absolute symbols with the same value Both MS link.exe and GNU ld.bfd handle it this way; one can have multiple object files defining the same absolute symbols, as long as it defines it to the same value. But if there are multiple absolute symbols with differing values, it is treated as an error. Differential Revision: https://reviews.llvm.org/D71981
