g1{pre|post}barrierslowid generation reaches for card table address, but it might not be available if barrier set does not support it. Reliably asserts with Epsilon.

Bug: https://bugs.openjdk.java.net/browse/JDK-8199511 Fix: http://cr.openjdk.java.net/~shade/8199511/webrev.01/ This is arch-specific fix: - c1Runtime1aarch64: copy-pasted the check block from g1prebarrierslowid - c1Runtime1arm: added check block for both g1{pre|post}slowid - c1Runtime1ppc: already implemented - c1Runtime1s390: already implemented - c1Runtime1sparc: already implemented - c1Runtime1x86: copy-pasted the check block from g1prebarrierslowid Testing: x8664 build, Epsilon tests, (running with submit-hs repo now) Thanks, -Aleksey

I just stumbled over the same thing.

Patch looks good to me!

Thanks, Roman
