In rL372232 <https://reviews.llvm.org/rL372232>, we treated names showing up in profile as not cold when profile-sample-accurate is enabled. This caused 70k size regression in Chrome/Android. The patch put a guard and only enable the change when profile symbol list is available, i.e., keep the old behavior when profile symbol list is not available.
