    avcodec/{arm,neon}/mpegvideo: Use intra scantable to unquant H263 intra
Forgotten in 70a7df049c411d9247eb6075720c84196c3e55e8.

Using the wrong scantable matters for codecs for which both scantables
can differ, namely the MPEG-4 decoder and the WMV1/2 codecs.

For WMV1 it can lead to wrong output in case the IDCT permutation
is FF_IDCT_PERM_PARTTRANS, because in this case the entries of
of the intra scantable's raster end are not always <= the corresponding
entries of the inter scantable's raster end when the former is
initialized via ff_wmv1_scantable[1] and the latter via ff_wmv1_scantable[0].
FF_IDCT_PERM_PARTTRANS is used iff the Neon IDCT is used (for both arm
and aarch64).* Said IDCT is not used during FATE, so that this issue
went unnoticed.

WMV2 uses the same scantables, but uses a custom IDCT
which always uses FF_IDCT_PERM_NONE for which the inter_scantable,
so that the output is always correct for it.

The scantable for MPEG-4 can change mid-stream (for the decoder),
but since c41818dc5dc14eb944761204e7b0ac179a6dcd1a only the intra
scantable is updated, so that both scantables can get out of sync.
In such a case the unquantize intra functions could unquantize
an incorrect number of coefficients.

Using raster_end of the wrong scantable can also lead to an
unnecessarily large amount of coefficients unquantized.

*: FF_IDCT_PERM_SIMPLE and FF_IDCT_PERM_TRANSPOSE would also not work,
but they are not used at all by arm and aarch64.

    tests/checkasm: Add mpegvideo unquantize test
This adds a test for the mpegvideo unquantize functions.

It has been written in order to be able to easily bench
these functions. It should be noted that the random input
fed to the tested functions is not necessarily representative
of the stuff actually occuring in the wild. So benchmarks should
be taken with a grain of salt; but comparisons between two functions
that do not depend on branch predictions are valid (the usecase
for this is to port the x86 mmx functions to use xmm registers).

During testing I have found a bug in the arm/aarch64 neon optimizations
when using the LIBMPEG2 permutation (used by FF_IDCT_INT): The code
seems to be based on the presumption that the remainder of the number
of coefficients to process is always <= 4 mod 16. The test therefore
sometimes fails for these arches.

Hint: I am not certain that 16 bits are enough for the intermediate
values of all the computations involved; e.g. both FLV and MPEG-4
escape values can go beyond that after the corresponding
multiplications. The input in this test is nevertheless designed
to fit into 16 bits.

    avcodec/{arm,neon}/mpegvideo: Fix h263 unquantize functions
These functions currently operate on the assumption that the number
of coefficients to process is always of the form 16k+m with m<=4 or >8.
Yet this is not true when the IDCT permutation is of type FF_IDCT_PERM_LIBMPEG2
(i.e. when FF_IDCT_INT is in use).

    avcodec/x86/mpegvideo: Use correct inline assembly constraints
The H.263 unquantize functions modified an input parameter.
(And they did so since this code was added in
7f3f5ec87bcbf244fce49ffdb476d4ae6e523af6. I am surprised
that this didn't cause issues, particularly with the intra function.)

    avcodec/x86/mpegvideo: Improve unquantizing MPEG-2 intra blocks
Unquantizing involves calculating
    (block[j] * qscale * quant_matrix[j]) / 16
where / rounds towards zero. Arithmetic right shifts
naturally round towards -inf, so the earlier code
calculated the absolute value first, then used a right-shift
and then negated the result if necessary.

This commit uses a different procedure: It biases the product
for negative values of block[j] by 0xf. The combination of
this and the arithmetic right shift is the same as rounding
towards zero.

Furthermore, a write-only store to mm7 has been removed.

Benchmarks:
dct_unquantize_mpeg2_intra_c:                          214.3 ( 1.00x)
dct_unquantize_mpeg2_intra_mmx (old):                   43.0 ( 4.98x)
dct_unquantize_mpeg2_intra_mmx (new):                   28.4 ( 7.56x)

(The bitexact flag and the test for correctness have beem removed
from checkasm for the benchmarks.)

    avcodec/x86/mpegvideo: Don't duplicate register
Currently several inline ASM blocks used a value as
an input and rax as clobber register. The input value
was just moved into the register which then served as loop
counter. This is wasteful, as one can just use the value's
register directly as loop counter.
