Hi,
although BRIG_OPCODE_DEBUGTRAP isn't currently generated by gcc trunk,
some experimental patches that I have do and it is one of the rare cases
where registers in zeroth operand are input, so it should be recognized
as such by hsa_insn_basic::op_output_p.

* hsa.c (hsa_insn_basic::op_output_p): Add BRIG_OPCODE_DEBUGTRAP
to the list of instructions with no output registers.
