5022ee43fc Make branching work :) Simply allow output variables as valid 
operand inputs when they've been assigned already.

7636aac54b Fix glDrawElements + VBO rendering when ptr/offset is not zero. 
When an index VBO is bound, glDrawElement's indices pointer is really an
offset into the element buffer.  Add that offset to the prims[i].start
value before calling pipe->draw_elements().
Fixes vbo.c conform test.

4664261f8d Fix vertex cache bug that allows multiple vertices to fall into the same slot. 
Need to set the slot's bit in draw->vcache.referenced even when there was a
cache hit since flushing the primitive buffer will have cleared the bitfield
but not the cache's vertex indexes.

Fixes a bug found when drawing long triangle fans but could be hit by other
prim types as well.

An alternate fix would be to call draw_vertex_cache_invalidate() from
draw_vertex_cache_unreference().

40e46d0727 In get_vertex(), slot was computed using & 31. Replace with % VCACHE_SIZE. 
Also, assert that index is not too large before indexing array.
