[GOOGLE] don't overwrite precomputed loop bound in AutoFDO

If a loop is cunrolled/vectorized, the AutoFDO computed trip count will be very small. This patch disallows overwritting of precomputed loop bound in AutoFDO mode. Bootstrapped and passed regression test. Performance test on-going. OK for Google branches? Thanks, Dehao Index: tree-ssa-loop-nite
