The peephole2 has logical_operand which means it accepts register so
simplify_const_binary_operation will fail as we have a register here and not
just an int.

proposed patch
This patch enables the peephole2 only if operands[1] and operands[2] are
constant.
An alternative patch would add a check for CONSTANT_P (operands[1]) &&
CONSTANT_P (operands[2]) in the peephole's C code.
