i965/fs: Fix copy propagation of load payload for double operands
Specifically, consider the size of the data type of the operand to compute the number of registers written. v2 (Sam): - Fix line width (Jordan). - Add an assert (Jordan). - Use REG_SIZE in the calculation of regs_written (Curro) v3 (Sam): - Fix assert and calculation of regs_written (Curro).
