Whenever XF memory changes, Dolphin will flush the vertex manager. This is the right thing to do generally but one area that is very inefficient is with GPU skinning (animation on the GPU). Many character meshes will take numerous draws to render because the per-vertex skinning matrix changes between draw calls, triggering a flush.

GPUs do better crunching through data. So it'd be more efficient if we bundled these draws together.

Doing so requires us to not only remove the extraneous flushing but also change the vertex shader generation which currently assumes each vertex has an index into a (relatively tiny) skinning buffer.
