Chandler Carruth d410eaba04 Revert r155365, r155366, and r155367. All three of these have regression
test suite failures. The failures occur at each stage, and only get
worse, so I'm reverting all of them.

Please resubmit these patches, one at a time, after verifying that the
regression test suite passes. Never submit a patch without running the
regression test suite.
