94a61241b0 libFLAC: Add a workaround for a bug in MSVC2105 update2 
MSVC2105 update2 compiles the C code:

    abs_residual_partition_sums[partition] =
                  (FLAC__uint32)_mm_cvtsi128_si32(mm_sum);

into this:

    movq    QWORD PTR [rsi], xmm2

while it should be:

    movd    eax, xmm2
    mov     QWORD PTR [rsi], rax

With this patch, MSVC emits:

    movq    QWORD PTR [rsi], xmm2
    mov     DWORD PTR [rsi+4], r9d

so the price of this workaround is 1 extra write instruction per
partition.
