[PATCH] D80047: Don't tail merge EHPads

[Eli Friedman via Phabricator via llvm-commits]

Could you explain why you think this is the right thing to do?

At first glance, I don't see any obvious problem with tail merging in this context unless this is illegal due to "region" restrictions (merging code in different unwind handlers).  And if the issue is in fact a problem with merging across regions, this fix is clearly insufficient; isEHPad() is only true for the first MBB of an unwind handler.
