The opcode_desc tables are useful for several purposes other than
disassembling the program: Finding out whether an instruction is
three-source in the optimizer and instruction compaction code,
printing out instructions at the IR level and validating assembled
programs -- It seems like brw_eu.c next to other EU ISA auxiliary code
is a better fit than the disassembler.
