r600: relax stride/alignment requirements for vertices
seems hw can do unaligned accesses and unaligned strides
removes extra conversion when using vbo's
however I needed to switch 3 component byte format to 4 component formats
for tests to pass. Somewhat sililar to GL_SHORT fix done earlier
removes assert and gains +2 piglit especially draw-vertices
