Description

Fix for bug 5442338 (crash in deoptimization): when optimized code calls deoptimization stub, check if the function was already deoptimized previously before attempting to restore unoptimized code. Add test case when optimized code of a deoptimized function is several time on stack, and deoptimization occurs after the function was already deoptimized.
