This makes the stack/lock analysis less lock error prone.\nExtra Barrier assertions and condition variable time out is now returned as a\nboolean both from Barrier and ConditionVariable::Wait.\n\n2 threaded host x86-64 interpret-only numbers from 341 samples:\nBefore change: Avg 176.137ms 99% CI 3.468ms to 1060.770ms\nAfter change: Avg 139.163% 99% CI 3.027ms to 838.257ms\nReduction in average compile time after change is 20.9%.\nSlow-down without change is 26.5%.\n\nBug: 17471626 - Fix bug where RegTypeCache::JavaLangObject/String/Class/Throwable\ncould return unresolved type when class loading is disabled.\nBug: 17398101\n\nChange-Id: Id59ce3cc520701c6ecf612f7152498107bc40684\n"
