Patch looks good.
FWIW, the fillInStackTrace case is removed in OpenJDK 9 by JDK-8076112
 (which adds HotSpotIntrinsicCandidate), but I can't see anything
in that change which warrants its removal. I suspect it may be more
related to the stack walking changes in 9.
Elements of JDK-8076112 were backported for the recent security fix,
JDK-8223511. I wonder if backporting the rest may be a worthwhile
debugging aid for intrinsics on 8u, especially with regard to the
varying support on different architectures.
