Fixed 6919886: Sweep CodeCache more aggressively to reduce its usage for CompileTheWorld

Current sweeping frequency is not enough to keep CodeCache
clean when compiling big jar files with CompileTheWorld.

Add safepoint after CompileTheWorldSafepointInterval (100)
compilations and do full sweep of CodeCache each time.
