i965: Use SET_FIELD to safety check our x/y offsets in blits.
The earlier assert made sure that our math didn't exceed our bounds, but this makes sure that we don't overflow from the high bits X into the low bits of Y. We've already put checks in intel_miptree_blit(), but I've wanted to expand the type in our protoype from short to uint32_t, and we could get in trouble with intel_emit_linear_blit() if we did. v2: Add Ken's comment about the funny language extension used.
