Given sets of UsingBlocks and DefBlocks, compute the set of LiveInBlocks.
This is basically a subgraph limited by DefBlocks and UsingBlocks.

◆ getUserBB()

static |
Helper function for finding a block which should have a value for the given user.
For PHI-nodes this block is the corresponding predecessor, for other instructions it's their parent block.
