  [LoopUnroll] Record conditional latch info (#182403)

This patch makes no functional change and so introduces no new tests or
documentation, but it is not merely refactoring.

This patch gathers conditional latch info needed for PR #179520, which
fixes block frequencies when LoopUnroll converts a conditional latch in
an unrolled loop iteration to unconditional. Without PR #179520, this
patch is useless and should not land.
