[PATCH] D15564: [ELF] - Optimize .eh_frame section: remove CIE if all FDEs referencing it were removed.

[George Rimar via llvm-commits]

grimar added a comment.

I had to revert it in r256693. Unfortunately I lost changes in void EHOutputSection<ELFT>::writeTo() when resolved conflicts during commit. Since test didn`t catch that, I think it also need to be improved. I`ll improve the test and recommit later.
That lost change should not affect on perfomance anyhow though.
