Torok Edwin 15417383b9 Fix memory leak in liveintervals: the destructor for VNInfos must be called, 
otherwise the SmallVector it contains doesn't free its memory.
In most cases LiveIntervalAnalysis could get away by not calling the destructor,
because VNInfos are bumpptr-allocated, and smallvectors usually don't grow.
However when the SmallVector does grow it always leaks.

This is the valgrind shown leak from the original testcase:
