The current trap handler defined:
.set SQ_WAVE_EXCP_FLAG_USER_MATH_EXCP_SHIFT , 0
.set SQ_WAVE_EXCP_FLAG_USER_MATH_EXCP_SIZE , 6
.set SQ_WAVE_TRAP_CTRL_MATH_EXCP_SHIFT , 0
.set SQ_WAVE_TRAP_CTRL_MATH_EXCP_SIZE , 6
However, the ALU exception in EXCP_FLAG_USER go from bit 0 (alu_invalid)
to bit 6 (alu_int_div0), making it a total of 7 bits, not 6. Similarly,
the corresponding bits in TRAP_CTRL go from bit 0 to 6 as well.
Fix the incorrect size to be sure to properly detect the int_div0
exception.
