i965: Split brw_emit_reloc into brw_batch_reloc and brw_state_reloc. 

brw_batch_reloc emits a relocation from the batchbuffer to elsewhere.
brw_state_reloc emits a relocation from the statebuffer to elsewhere.

For now, they do the same thing, but when we actually split the two
buffers, we'll change brw_state_reloc to use the state buffer.
