This general Graal update also fixes JDK-8204914 and includes a few other fixes from Graal.  Unfortunately the webrev is fairly noisy because of blank lines inserted because of copyright adjustment and the addition of @Override annotations in JVMCI.

Primarily this is about making a strong distinction between runtime and compiler objects and state and hiding anything which lets you bridge that boundary without be careful.  Mostly it doesn't change the way JVMCI works apart from some changes to the HotSpotSpeculationLog implementation and the associated changes in Graal.  These changes are binary incompatible with previous versions of JVMCI.  Given the limitations of webrev I can't easily provide a webrev which shows just this change.
