  Log Message:
  -----------
  [MC,ELF] Set sh_entsize for SHT_INIT_ARRAY/FINI_ARRAY/PREINIT_ARRAY (#226875)

Match GNU Assembler: set sh_entsize to 4/8, regardless of sh_size. This
is mostly cosmetic: sh_entsize is not a useful member for non-merge
sections.
When clang-produced and GCC-produced objects are linked together, the
mismatch makes lld's output sh_entsize 0.
