glsl: Fix handling of OPCODE_PRINT for no registers case.
A register file value is unsigned so could never be -1. A
value of 0 also aliased to PROGRAM_TEMPORARY.
If an OPCODE_PRINT has no registers to print, set the register
file value to PROGRAM_UNDEFINED and check for that value when
executing this instruction.
