  Changed paths:
    M lld/ELF/InputFiles.cpp
    R lld/test/ELF/invalid/reloc-section-reordered.test
    A lld/test/ELF/reloc-sec-before-relocated.test

  Log Message:
  -----------
  [LLD][ELF] -  Allow relocation sections to appear before their target sections.

It allows handling cases when we have SHT_REL[A] sections before target
sections in objects.

This fixes https://bugs.llvm.org/show_bug.cgi?id=46632

which says: "Normally it is not what compilers would emit. We have to support it,
because some custom tools might want to use this feature, which is not restricted by ELF gABI"
