Teresa Johnson a65755ade0 [hot-cold-split] Only perform splitting in ThinLTO backend post-link
Summary:
Fix the new PM to only perform hot cold splitting once during ThinLTO,
by skipping it in the pre-link phase.

This was already fixed in the old PM by the move of the hot cold split
pass later (after the early return when PrepareForThinLTO) by r344869.
