    avcodec/x86/h264_idct: Remove redundant movsxdifnidn
Only exported (i.e. cglobal) functions need it; stride is already
sign-extended when it reaches any of the internal functions used here,
so don't sign-extend again.

    avcodec/x86/h264_idct: Don't use MMX registers in ff_h264_luma_dc_dequant_idct_sse2
It is ABI compliant and gives a tiny speedup here (and is 16B smaller).

Old benchmarks:
h264_luma_dc_dequant_idct_8_c:                          33.2 ( 1.00x)
h264_luma_dc_dequant_idct_8_sse2:                       16.0 ( 2.07x)

New benchmarks:
h264_luma_dc_dequant_idct_8_c:                          33.0 ( 1.00x)
h264_luma_dc_dequant_idct_8_sse2:                       15.0 ( 2.20x)

    avcodec/x86/h264_idct: Deduplicate generating constant
pw_1 is currently loaded in both codepaths. Generate it earlier instead.
Gives tiny speedups (15 vs 14.5 cycles) and reduces codesize.

    avcodec/x86/h264_idct: Fix ff_h264_luma_dc_dequant_idct_sse2 checkasm failures
ff_h264_luma_dc_dequant_idct_sse2() does not pass checkasm for certain
seeds, because the input to packssdw no longer fits into an int16_t,
leading to saturation, where the C code just truncates. I don't know
whether the spec contains provisions that ensure that valid input
must not exceed 16 bit or whether the such inputs (even if invalid)
can be triggered by the actual code and not only the test.

This commit adapts the behavior of the function to the C reference code
to fix the test. packssdw is avoided, instead the lower words are
directly transfered to GPRs to be written out. This has unfortunately
led to a slight performance regression here (14.5 vs 15.1 cycles).

Fixes issue #20835.
