[PATCH] Add a new opcode: OP_COPY.
This is needed to translate SSA back to normal form.
Maybe we should split this in two distinct ops: The first ones
correspond to the old OP_PHISOURCE (but if the same phisrc feed several
phi-nodes, we need sevarel distinct copy instruction); at this stage
they are the only instruction that can define a pseudo in multiple
places. The other ones being the "normal" copies.
