d7a4f8f8b9 Move MASK_ABS macro to libavcodec/mathops.h
This macro is only used in two places, both in libavcodec, so this
is a more sensible place for it.

Two small tweaks to the macro are made:

- removing the trailing semicolon
- dropping unnecessary 'volatile' from the x86 asm

79414257e2 mathops: fix MULL() when the compiler does not inline the function.
If the function is not inlined, an immmediate cannot be used for the
shift parameter, so the %cl register must be used instead in that case.

This fixes compilation for x86-32 using gcc with --disable-optimizations.

aaff3b312e mathops: change "g" constraint to "rm" in x86-32 version of MUL64().
The 1-arg imul instruction cannot take an immediate argument, only a register
or memory argument.

b181b8fb96 mathops: convert MULL/MULH/MUL64 to inline functions rather than macros.
This fixes unexpected name collisions that were occurring with variables
declared within the macros.
It also fixes the fate-acodec-ac3_fixed regression test on x86-32.

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:

a6493a8fbd Rename libavcodec/i386/ --> libavcodec/x86/.
It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
