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.

Runtime of the full 32x32 idct goes from 2446 to 2441 cycles (intra) or from 1425 to 1306 cycles (inter). Overall runtime is not significantly affected.

Runtime of all IDCTs together goes from 3327 to 2473 cycles (intra, i.e. ~35% faster) or from 2312 to 1448 cycles (inter, i.e. ~60% faster). Total decode time of ped1080p.webm goes from 8.086sec to 7.974sec (1.4% faster).

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).

Sub8x8 speed (w/o dc-only case) goes from ~750 cycles (inter) or ~735 cycles (intra) to ~415 cycles (inter) or ~430 cycles (intra). Average overall 16x16 idct speed goes from ~635 cycles (inter) or ~720 cycles (intra) to ~415 cycles (inter) or ~545 (intra) - all measurements done using ped1080p.webm.

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.

For that specific case (eob>3&&eob<=12), runtime of idct8x8 goes from 668 to 477 cycles. For all idct8x8, runtime goes from 521 to 490 cycles.

This allows us to load it only once, instead of twice, in this function.

Make register usage in macros explicit; change mulsub_2w_4x to use 2 instead of 3 temp registers.

(And in future, loopfilter or intra pred could be put in their own respective files also.)
