intra: merge consecutive 8bpp regions and remove dead code
vec: prevent link errors on older compilers, do not try to call missing funcs
intra: remove redundant 16bpp angular prediction code

intra: re-enable __forceinline for MSVC to recover perf of angular predictions
primitives: convert Setup_Vector_Primitives to a CPU mask instead of ID

This allows the testbench to isolate the functions added for a given arch

primitives: convert Setup_Assembly_Primitives to a CPU mask instead of ID

This allows the testbench to isolate the functions added for a given arch
primitives: build primitive list iteratively

Rather than collect all intrinsic primitives and then collect all assembly
primitives, do the process iteratively for each CPU capability.  This plausibly
allows an SSE41 intrinsic primitive to have higher priority than an SSE assembly
primitive.
intra: fix eoln damage
