Document it a little and possibly fix a bug in dxva2_vc1.

Use the @command{} tag when needed and cleanup the examples.

Without this, code like "shufps m0, m1, m2, 0xaa" would not work in CPUs
not supporting SSE2.

Using an unsigned variable avoids problems with overflows.
There is further no need for a 64-bit intermediate here.

This fixes a compile error on mingw32 when using p->thread
directly (as if it were a pointer) to track thread existence,
because the type is opaque and may be a non-pointer.

As old bits are shifted out of the accumulator, they cause signed
overflows when they reach the end.  Making the variable unsigned fixes
this.

The way these values are used, they should have an unsigned type.

It is used by the ADX decoder, and therefore needs to be exported in order to
work with shared libs.
