Dan Gohman d496b35af0 Don't cache PHI exit values from exhaustive evaluations, because ... an individual exhaustive evaluation reflects only the exit value implied by an individual exit, which may differ from the actual exit value of the loop if there are other exits. This fixes PR4477. llvm-svn: 74447		2009-06-29 20:34:13 +00:00
