2017-05-15move neon load/stores to a new fileJohann
Move the tran_low_t helper functions to a new file. Additional load/store functions will be added here. Change-Id: I52bf652c344c585ea2f3e1230886be93f5caefc3

files. During aosp builds with binutils-2.27, we're seeing linker error messages of this form: libvpx.a(subpixel_mmx.o): relocation R_386_GOTOFF against preemptible symbol vp8_bilinear_filters_x86_8 cannot be used when making a shared object subpixel_mmx.o is assembled from "vp8/common/x86/subpixel_mmx.asm". Other messages refer to symbol references from deblock_sse2.o and subpixel_sse2.o, also assembled from asm files. This change marks such symbols as having "protected" visibility. This satisfies the linker as the symbols are not preemptible from outside the shared library now, which I think is the original intent anyway. Change-Id: I2817f7a5f43041533d65ebf41aefd63f8581a452

Add support for everything except block sizes of 4. Performance is better but numbers will improve again when the variance optimizations land. BUG=webm:1423 Change-Id: I92eb4312b20be423fa2fe6fdb18167a604ff4d80
2017-05-04sub pixel variance neon: use generic varianceJohann
When a neon version is available it will be called. This allows decoupling the variance implementations and has no real downside. For most configurations, the call will be #define'd to the neon implementation. Change-Id: Ibb2afe4e156c5610e89488504d366b3e6d1ba712

2017-05-04neon variance: process two rows of 8 at a timeJohann
When the width is equal to 8, process two rows at a time. This doubles the speed of 8x4 and improves 8x8 by about 20%. 8x16 was using this technique already, but still improved a little bit with the rewrite. Also use this for vpx_get8x8var_neon BUG=webm:1422 Change-Id: Id602909afcec683665536d11298b7387ac0a1207
2017-05-04neon variance: add small missing sizesJohann
Some of the mixed sizes were missing. They can be implemented trivially using the existing helper function. When comparing the previous 16x8 and 8x16 implementations, the helper function is about 10% faster than the 16x8 version. The 8x16 is very close, but the existing version appears to be faster.
