Dan Gohman 52ed61204b 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. llvm-svn: 97126		2010-02-25 06:57:05 +00:00
