i965/fs: Perform CSE on load_payload instructions if it's not a copy.
Since CSE creates instructions, if we let CSE generate things register
coalescing can't remove, bad things will happen. Only let CSE combine
non-copy load_payloads.
E.g., allow CSE to handle this
load_payload vgrf4+0, vgrf5, vgrf6
but not this
load_payload vgrf4+0, vgrf5+0, vgrf5+1
