This removes chacha_vec_arm.S and chacha_vec.c in favor of unifying on upstream's code. Upstream's is faster and this cuts down on the number of distinct codepaths. Our old scheme also didn't give vectorized code on Windows or aarch64. BoringSSL-specific modifications made to the assembly: - As usual, the shelling out to $CC is replaced with hardcoding $avx. I've tested up to the AVX2 codepath, so enable it all. - I've removed the AMD XOP code as I have not tested it. - As usual, the ARM file need the arm_arch.h include tweaked. Speed numbers follow. We can hope for further wins on these benchmarks after importing the Poly1305 assembly. x86 --- Old: Did 1422000 ChaCha20-Poly1305 (16 bytes) seal operations in 1000433us (1421384.5 ops/sec): 22.7
