r212424 reverted a bogus change that had disabled -fdelete-dead-exceptions.

Re-confirmed - this happens after DSE1.

Then it is weird to treat is as regression, because r188666 didn't support -Og.
In any case, either RTL DSE shouldn't remove stores with REG_EH_REGION note on
it, or if it does remove them we need to clean up EH.
