When the candidate has been found, no need to derive others.

The -MD option (for enabling a dynamically linked crt) gets interpreted
as a cpp option for generating dependency information (into a file named
'-.d', when preprocessing to a pipe). We shouldn't be passing
any and all C compiler flags to armasm (which is a plain assembler,
only with cpp bolted on via gas-preprocessor), but these are the
main conflicting ones.

Older versions don't support all the features we test for now.

Only use PAL8 if palette is present, else use GRAY8 for pixfmt.

Instead of simulating a grayscale palette, use real grayscale pixels, if no
palette is actually defined.

1) each of the loops run within a single CTB, so the relevant reference
list is constant
2) when that CTB is, or lies on the same slice as, the current one, we
can use a simple access instead of a relatively expensive call to
ff_hevc_get_ref_list()

It makes no sense and cannot happen in any place from which this
function is called.

Use named constants instead of magic numbers, avoid using variables with
inverse meaning from what their name implies.

The if() around those loops ensures this condition is always false.

ff_hevc_deblocking_boundary_strengths() is never called if the
deblocking filter is disabled for the slice.

The Xvid IDCT is not MMX-specific.

This fixes cases where the scantable permuation would get overwritten by
the general idctdsp initialization.

Standalone GNU assembly is not used on x86.

sws_getCachedContext is not a full replacement for the function.
