Anna Thomas 7949f4529a [JumpThreading][LVI] Invalidate LVI information after blocks are merged 
Summary:
After a single predecessor is merged into a basic block, we need to invalidate
the LVI information for the new merged block, when LVI is not provably true for
all of instructions in the new block.
The test cases added show the correct LVI information using the LVI printer
pass.
