157ce21939 checkasm/sw_rgb: Revert test additions from e18b46d95f 
The unaligned width test cases fail on i386; we have an assembly
function of rgb24toyv12 which is enabled only within
"#if ARCH_X86_32 && HAVE_7REGS", which seems to fail these new
test cases for unaligned widths.

As that assembly function has existed for a long time in that form,
the issue probably isn't very recent, thus skip testing these cases
for now.

Once the assembly function has been fixed, these test cases can
be readded.

399bf3f040 avdevice/avfoundation: remove write-only variable 
The block_buffer was only ever written to but then never used in the
following code, making it unnecessary.

Fixes a "variable 'block_buffer' set but not used" compiler warning.

b4d9fa6cb9 compat: Fix the fallback definition of stdc_trailing_zeros 
While shifting "value" to left, we would iterate through all bits
of an unsigned long long, while we only expect to count through
"size * CHAR_BIT" bits; instead shift bits to the right and just
count the trailing zeros.

This fixes fate with MSVC.
