    avcodec/vc1dsp: Avoid negating unnecessarily
Due to the earlier "if (a1 < a0 || a2 < a0)" check
it is guaranteed that min(a1,a2) is < a0, allowing
simplifications.

    avcodec/x86/vc1dsp_loopfilter: Avoid imul
Multipliying a GPR by 0x01010101 splats a byte to a dword;
the intention was to avoid vector shuffles lateron, yet
this is not true because the byte splat necessitates
a byte->word conversion lateron.

    avcodec/x86/vc1dsp_loopfilter: Reduce number of GPRs used
Reuse the register that held pq for this instead of using
another one. This saves a push+pop on 32bit systems and avoids
REX prefixes on Unix64.

    avcodec/x86/vc1dsp_loopfilter: Avoid unnecessary PABSW
The loop filter is only active if min(a1,a2)<abs(a0)
which is done via masking. Ergo the sign of min(a1,a2)-abs(a0)
is known (always negative) and one does not need to use
PABSW to get its absolute value.

This gives a small speedup. Old benchmarks:

    avcodec/x86/vc1dsp_loopfilter: Use psignw when available
The VC1 loop filter uses something equivalent to
if (a0_sign ^ clip_sign) {
    if (clip_sign) d = -d;
} else d = 0;
which can be mapped to psignw.

    avcodec/x86/vc1dsp_loopfilter: Don't use MMX regs in horiz. loop filter
Using XMM registers in this SSSE3 function leads to fewer shuffles
when transposing the input; it also allows to combine calculating
a1 and a2. Because of this, codesize is the same as before (on Unix64)
although MMX instructions are shorter.

Old benchmarks:
  vc1dsp.vc1_h_loop_filter4_bestcase_c:           3.0
  vc1dsp.vc1_h_loop_filter4_bestcase_ssse3:      32.0 ( 0.09x)
  vc1dsp.vc1_h_loop_filter4_worstcase_c:         42.9
  vc1dsp.vc1_h_loop_filter4_worstcase_ssse3:     31.9 ( 1.35x)

New benchmarks:
  vc1dsp.vc1_h_loop_filter4_bestcase_c:           3.0
  vc1dsp.vc1_h_loop_filter4_bestcase_ssse3:      29.9 ( 0.10x)
  vc1dsp.vc1_h_loop_filter4_worstcase_c:         43.7
  vc1dsp.vc1_h_loop_filter4_worstcase_ssse3:     29.9 ( 1.46x)

Hint: checkasm's benchmark always uses the same buffer that is
partially updated by the horizontal loop filter function (the
middle two of eight columns are updated using word-sized stores).
They therefore lead to store-to-load-forwarding failure. If
checkasm_alternate were used to alternate between two buffers,
the benchmarks would be as follows:

  vc1dsp.vc1_h_loop_filter4_worstcase_c:         23.9
  vc1dsp.vc1_h_loop_filter4_worstcase_ssse3:     16.3 ( 1.47x)

New benchmarks:
  vc1dsp.vc1_h_loop_filter4_bestcase_c:           3.0
  vc1dsp.vc1_h_loop_filter4_bestcase_ssse3:      15.1 ( 0.20x)

  vc1dsp.vc1_h_loop_filter4_worstcase_ssse3:     15.2 ( 1.55x)

Notice that at some callsites, the partially modified buffer
is immediately reloaded again*, so that both scenarios can happen.

*: See the TT_4X4 and TT_4X8 cases at the end of vc1_p_h_loop_filter()
or vc1_b_h_intfi_loop_filter() or the luma field blocks in
vc1_p_h_intfr_loop_filter().

    avcodec/x86/vc1dsp_loopfilter: Don't use MMX regs
Up until now ff_vc1_v_loop_filter4_ssse3 used MMX registers
despite being an SSSE3 function. Porting it to XMM registers
didn't lead to any change in benchmarks here, but abides
by the ABI (one function less that does not omit emms).
Unfortunately the size of the function increased by 64B
by this.
