[OpenJDK 2D-Dev] Java2d code using @ForceInline or @Stable annotations

[Philip Race]

The jigsaw team would need to sign off on any changes
to the module graph and in addition I think the VM team
might have some input on this since I don't think this
is intended to be used other than extremely sparingly.
I see @Stable used only by String and java.lang.invoke
which has deep ties to the VM.
In other words I am not sure we should do this or if, for ForceIine,
it would bring any benefits over what hotspot is doing without prompting.
