vp9/x86: idct_add_16x16_ssse3. Currently only dc-only and full 16x16. Other subforms will follow in the near future. Total decoding time of ped1080p.webm goes from 9.7 to 9.3 seconds. DC-only goes from 957 -> 131 cycles, and the full IDCT goes from ~4050 to ~745 cycles.

vp9/x86: use explicit register for relative stack references. Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.

vp9/x86: use explicit register for relative stack references. Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.

vp9/x86: use explicit register for relative stack references. Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.

vp9/x86: use explicit register for relative stack references. Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.

vp9/x86: idct_32x32_add_ssse3. Sub-IDCTs will follow later. ped1080.webm goes from 9.295s to 8.191s (13.5% faster). The IDCT itself goes from 4372 (intra) or 4337 (inter) to 403 (intra) or 329 (inter) cycles for the DC-only form, 23755 (intra) or 23723 (inter) to 3497 (intra) or 3607 (inter) cycles for the no-DC form, which averages from 23393 (intra) or 16612 (inter) to 3449 (intra) or 2392 (inter) for all 32x32s together, i.e. about ~7x faster (all tests done on ped1080p.webm).

vp9/x86: idct_add_16x16_ssse3. Currently only dc-only and full 16x16. Other subforms will follow in the near future. Total decoding time of ped1080p.webm goes from 9.7 to 9.3 seconds. DC-only goes from 957 -> 131 cycles, and the full IDCT goes from ~4050 to ~745 cycles.
