92436e8ad9 vp9: implement top/left half (4x4) sub-8x8-IDCT. 
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.

b2045c44a9 vp9: split pre-load of 11585x2 out of 1d idct macro. 
This allows us to load it only once, instead of twice, in this function.

f9a0d4c6e0 vp9: minor refactorings in idct ssse3 assembly. 
Make register usage in macros explicit; change mulsub_2w_4x to use 2
instead of 3 temp registers.

8729964b99 vp9: split x86 assembly in two files. 
(And in future, loopfilter or intra pred could be put in their own
respective files also.)

5b073da7a1 doc: add script to compute texi files dependencies 
Replace the inline awk script with a Perl script which tracks the
dependencies recursively.

This allows to correctly track dependencies for files including files
with a second level include (for example: ffmpeg-devices.texi ->
devices.texi -> outdevs.texi).

This also adds a dependency on perl for computing the dependencies, which
should not be a problem since perl is already required all the way for
building documentation.

This is a variant of commit 628ceac652
which was reverted due to out-of-tree build failure.
