[jdk11u-dev] RFR: 8270533: AArch64: size_fits_all_mem_uses should return false if its output is a CAS

[Alexey Pavlyutkin]

I'd like to backport JDK-8190753 to jdk11u

The original patch applied cleanly

Testing: original patch does not have verification tests. Regression: hotspot_tier2 (arm64/20.04 LTS)
