This work is sponsored by, and copyright, Google. This reduces the code size of libavcodec/aarch64/vp9itxfm_neon.o from 19496 to 14740 bytes. This gives a small slowdown of a couple of tens of cycles, but makes it more feasible to add more optimized versions of these transforms. Before: vp9_inv_dct_dct_16x16_sub4_add_neon: 1036.7 vp9_inv_dct_dct_16x16_sub16_add_neon: 1372.2 vp9_inv_dct_dct_32x32_sub4_add_neon: 5180.0 vp9_inv_dct_dct_32x32_sub32_add_neon: 8095.7 After: vp9_inv_dct_dct_16x16_sub4_add_neon: 1051.0 vp9_inv_dct_dct_16x16_sub16_add_neon: 1390.1 vp9_inv_dct_dct_32x32_sub4_add_neon: 5199.9 vp9_inv_dct_dct_32x32_sub32_add_neon: 8125.8 This is cherrypicked from libav commit 115476018d2c97df7e9b4445fe8f6cc7420ab91f.
