Srdjan Mitrovic	fe4a5d7672	This adds a mechanism to invalidate code that was generated in the background. The invalidation can happen if a relevant event was invoked between background compilation start and installation of code (e.g, field type invalidatet, subclasses added, deferred loading). ... We introduce 3 invalidation generation counters: CHA, field and library prefixes. If one of the counters was incremented during compilation, and is relevant for that compilation, the code installation is skipped since that code may have become invalid in the meantime. Add BackgroundCompilationResult that remembers the 3 invalidation generations. The generational counter can rollover, which is OK.
