  [VPlan] Recalculate VPDT in handleUncountableExitsWithSideEffects (#203233)

In the loop before we're modifying the CFG, but this invalidates the
dominator tree. We need to recalculate since we query it later on. I
can't really think of a test case for this, if anything using the
stale dominator tree with the extra branch will make the dominance
queries more conservative. But it's probably something we should fix.
