RFR: 8141633: Implement VarHandles/Unsafe intrinsics on AArch64

[Andrej Golovnin]

Hi Andrew,

src/cpu/aarch64/vm/macroAssembler_aarch64.cpp

2144 // A generic CAS; success or failure is in the EQ flag.
2145 // A generic CAS; success or failure is in the EQ flag.  A weak CAS

I think the line 2144 can be removed.

Best regards,
Andrej Golovnin
