234 "execution" of the Phi operation requires "remembering" which block
235 control came from. The Phi operation takes on the value corresponding to
247 Phi nodes:
251    Phi node in this case.
257 Phi nodes directly, if convenient. In this case, it is really really
258 easy to generate the Phi node, so we choose to do it directly.
345 issue is that when we create the Phi node in the merge block, we need to
346 set up the block/value pairs that indicate how the Phi will work.
347 Importantly, the Phi node expects to have an entry for each predecessor
354 value for code that will set up the Phi node.
596 need it to create the Phi node, we remember the block that falls through
613 know the incoming value for the starting value, we add it to the Phi
614 node. Note that the Phi will eventually get a second value for the
