ir: Give ir_instruction a print visitor helper.
...
This avoids spamming each file with includes of ir_print_visitor.h
because someone was doing debugging at some point, and is less typing
when doing debugging.

ir_copy_propagation: Return true if we optimized out any assignments.
...
This may trigger other optimization phases to make more progress themselves.

ir_copy_propagation: Handle swizzles and array derefs on LHS of assign.
...
This improves the ACP to not get cleared when more complicated assignments
occur, cleaning up more redundant copies in programs.

ir_copy_propagation: New pass to rewrite dereferences to avoid copies.
...
This is pretty basic. Right now it only handles pure assignments --
same type on each side, no swizzling, and only within basic blocks.
