i965/vec4: Port regions_overlap() to the vec4 IR.

This is copy-pasted almost line by line from the FS back-end. The only reason it cannot be implemented in terms of backend_reg is that the backend_reg::nr field doesn't have the same meaning for uniforms on both back-ends. It could be easily deduplicated by using a template function.
