g1_{pre|post}_barrier_slow_id 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:
- c1_Runtime1_aarch64: copy-pasted the check block from g1_pre_barrier_slow_id
- c1_Runtime1_arm: added check block for both g1_{pre|post}_slow_id
- c1_Runtime1_ppc: already implemented
- c1_Runtime1_s390: already implemented
- c1_Runtime1_sparc: already implemented
- c1_Runtime1_x86: copy-pasted the check block from g1_pre_barrier_slow_id
Testing: x86_64 build, Epsilon tests, (running with submit-hs repo now)
Thanks, -Aleksey
