i965: Implement ARB_shader_stencil_export (gen9+)
v2: remove useless source_stencil_to_render_target (Ken)
Squash in the actual packing function, which also got to
v2:
Move the definition of the OPCODE outside of FB_WRITE opcodes (Matt)
Reorder the regioning to be in VWH order (Matt)
Don't retype src in the backend, just assert instead (Matt)
Rename the debug prints to something better (Matt)
