3d05c1fbec Make the jump-table section-relative for x86_64 with PIC enabled. 
This allows to get rid of the macho64 specific hack that moves them
to rodata (with worse cache behaviour) and avoids textrels which
e.g. Gentoo does not allow for x86_64 libraries.

5e7dfb7de1 Move COPY3_IF_LT to lavc/mathops.h 
This obscure macro is only used in motion_est.c so having it in lavc
makes more sense.  See discussion here:

b1159ad928 refactor and optimize scalarproduct 
29-105% faster apply_filter, 6-90% faster ape decoding on core2
(Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.)
9-123% faster ape decoding on G4.

952e872198 Drop unused args from vector_fmul_add_add, simpify code, and rename 
The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively.  This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.

Patch by John Adcock, dscaler.johnad AT googlemail DOT com.

4f717c69ed idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. 
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).
