1. Always inline (Clang previously ignored inline and got 25% slower) 2. SIMD everywhere other than x86 gcc: non-SIMD is only faster in my desktop with gcc; with Clang on my desktop, SIMD is 50% faster than non-SIMD. 3. Allocate 4x memory instead of 2x when running out of space: on old Android devices with Linux kernel 3.10 (e.g., Nexus 6P, 5X), the alloc/memcpy will triger a major bottleneck in kernel (30% of the running time). Such bottleneck goes away (the kernel is no longer doing stupid things during alloc/memcpy) in Linux kernel 3.18 (e.g., Pixel), and that's why DAA is much faster on Pixel than on Nexus 6P. I think maybe I should adopt SkRasterPipeline for device-specific optimizations.
