Dan Gohman 8566963713 Make LoopSimplify change conditional branches in loop exiting blocks ... which branch on undef to branch on a boolean constant for the edge exiting the loop. This helps ScalarEvolution compute trip counts for loops. Teach ScalarEvolution to recognize single-value PHIs, when safe, and ForgetSymbolicName to forget such single-value PHI nodes as apprpriate in ForgetSymbolicName. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97126 91177308-0d34-0410-b5e6-96231b3b80d8		2010-02-25 06:57:05 +00:00
