Most important fix is that VNLength is now restricted to the subset
of value numbers that are Bounds in the RangeAnalysis.

Experimental library that tracks the length of memory.
...
For each pointer, we start tracking (starting from the allocation or an array declaration)
1) how long is the chunk of memory allocated
2) where the current pointer is in this chunk of memory.
This information might not always exist, but when it does, it is reliable.
Currently only works intraprocedurally.
