8040024: BranchOptimizer produces bad code for NaN FP comparison Reviewed-by: jlaskey, lagergren

8039044: Expand undefined intrinsics for all commutative combinators of scrict undefined checks Reviewed-by: jlaskey, hannesw

8038799: Guard and unbox boxed primitives types on setting them in Properties to avoid megamorphisism Reviewed-by: attila, jlaskey

8027043: Turn global accesses into MethodHandle.constant, with one chance of reassignment, e.g. x = value occuring once in the global scope is ok, twice is not. Reviewed-by: attila, sundar, jlaskey

8038416: Access to undefined scoped variables deoptimized too much Reviewed-by: jlaskey, lagergren

8038406: Testability: as a first step of moving loggers away from the process global space, the Debug object now supports logging POJOs from log entries as an event queue, which can be introspected from test scripts. This is way better than screen scraping brittle and subject-to-change log output. Reviewed-by: attila, hannesw, sundar

8033334: Make sure that scope depth information is maintained in the RecompilableScriptFunctionDatas, to avoid unnecessary slow proto linkage when doing on demand compilation Summary: Compute RecompiledScriptFunctionDatas eagerly, annotate them with scope depth information and use them in recompilations. Reviewed-by: attila, hannesw, jlaskey

8037086: Check that deoptimizing recompilations are correct Reviewed-by: attila, lagergren

8036986: Test should check that correctly type is returned running with optimistic. If optimistic assumption was wrong we should get the right one. Summary: This uses the inspection framework for generated code to ensure optimisim. Reviewed-by: attila, lagergren Contributed-by: matherey.nunez@oracle.com

8037177: -Dnashorn.optimistic should be enabled by default, meaning that it has to be explicitly set to false to run with the jdk 8 style conservative types Summary: This will be the new default setting, so the explicit flag should be removed, and instead reverse checked for explicitly DISABLED optimistic types. In the future, we might remove the flag altogether. Reviewed-by: attila, hannesw

8036127: Prototype filter needs to be applied to getter guard as well, not just getter Summary: This manifests itself as a bug in optimistic types, as inner functions may access properties of the wrong type, but it is also a bug in tip. Without optimistic types, we have been unable to find a reproducer due to more similar PropertyMaps Reviewed-by: attila, jlaskey, sundar
