    Fix lld warning "SHF_MERGE section size must be a multiple of sh_entsize"

    Merge commit 56decd982dc0 from llvm git (by Fangrui Song):

      [ELF] Allow invalid sh_size%sh_entsize!=0 for non-SHF_MERGE sections

      Fixes https://bugs.llvm.org/show_bug.cgi?id=45370
      Fixes https://github.com/Clozure/ccl/issues/273

      .stab holds a table of 12-byte entries. GNU as before 2.35 incorrectly
      sets sh_entsize(.stab) to 20 on 64-bit architectures:
      https://sourceware.org/bugzilla/show_bug.cgi?id=25768

      We should not emit the confusing error:
      "SHF_MERGE section size (...) must be a multiple of sh_entsize (20)

      Differential Revision: https://reviews.llvm.org/D77368

    Direct commit to stable/12, since newer branches have this fix already.
