Previously, the SPIR-V instruction printer was always printing the first operand of an `OpConstant`'s literal value as one of the fixed operands. This is incorrect for 64-bit values, where the first operand is actually the value's lower-order word and should be combined with the following higher-order word before printing. This change fixes that issue by waiting to print the last fixed operand of `OpConstant` instructions until the variadic operands are ready to be printed, then using `NumFixedOps - 1` as the starting operand index for the literal value operands.
