959ecb2eec LoopVectorize: LoopSimplify can't canonicalize loops with an indirectbr in it, don't assert on those cases. 
Fixes PR16139.

db2367512e LoopVectorizer: Fix a bug in the code that updates the loop exiting block. 
LCSSA PHIs may have undef values. The vectorizer updates values that are used by outside users such as PHIs.
The bug happened because undefs are not loop values. This patch handles these PHIs.
