RFR: 8317266: Move nmethod::check_all_dependencies to codeCache.cpp and mark it NOT_PRODUCT

[Evgeny Astigeevich]

`nmethod::check_all_dependencies` goes over live nmethods and checks if any of nmethod's dependencies have been invalidated. It is public static and does not use any private/protected members of nmethod. There are no other uses of `nmethod::check_all_dependencies` but in `CodeCache::mark_for_deoptimization` of codeCache.cpp. The use is in NOT_PRODUCT code. The function has not-product code dependant on not-product `TraceDependencies`. If `TraceDependencies` is enabled in a release build, the code will not be available and there will be significant performance impact. See https://bugs.openjdk.org/browse/JDK-7194669 for details.

As the function is only used in debug builds, depends on not-product code, does not use any specifics of nmethods and has only one use, it is reasonable to move it to codeCache.cpp and to make it a standalone static function guarded by `#ifndef PRODUCT`

Tested with fastdebug and release builds:
- [x] gtest
- [x] tier1
