ARM64: Workaround for the callee saved FP registers and SIMD.
Treat as scheduling barriers those vector instructions whose live ranges exceed the vectorized loop boundaries. This is a workaround for the lack of notion of SIMD register in the compiler; around a call we have to save/restore all live SIMD&FP registers (only lower 64 bits of SIMD&FP registers are callee saved) so don't reorder such vector instructions. Test: 706-checker-scheduler, test-art-host, test-art-target Bug: 69667779 Change-Id: I31e57518339d41545a0c519f7299afe381a8286c
