ART: ARM64: Optimize frame size for SIMD graphs. For SIMD graphs allocate 64 bit instead of 128 bit on stack for each FP register to be preserved by the callee in the frame entry as ABI suggests (currently 64-bit registers are preserved but more space on stack is allocated). Note: slow paths still require spilling full 128-bit Q-Registers for SIMD graphs due to register allocator restrictions. Test: test-art-target. Change-Id: Ie0b12e4b769158445f3d0f4562c70d4fb0ea7744
