llvmpipe: implement scissor testing
The scissor test is implemented as another per-quad operation in
the JIT code. The four scissor box params are passed via the
lp_jit_context. In the JIT code we compare the quad's x/y coords
against the clip bounds and create a new in/out mask that's AND'd
with the main quad mask.
Note: we should also do scissor testing in the triangle setup code
to improve efficiency. That's not done yet.
