 @item Tree level if-conversion for vectorizer
 
 This pass applies if-conversion to simple loops to help vectorizer.
 We identify if convertible loops, if-convert statements and merge
 basic blocks in one big block.  The idea is to present loop in such
 form so that vectorizer can have one to one mapping between statements
