Description
Convert vmIntrinsics::SID to enum class to provide better type safety.

Also, put this enum class in the top level, so it can be forward-declared. I.e.,

enum class vmIntrinsicID : int;

This avoids excessive inclusion of vmIntrinsics.hpp (which currently is included indirectly in almost every hotspot source files).
