Here I think EXPR_LOC_OR_HERE (TREE_OPERAND (t, 1)) is better.
Why? TREE_OPERAND (t,1) is a dummy tree that we only use for its code.
Of course, currently it doesn't matter because we don't
SET_EXPR_LOCATION on either the MODOP_EXPR or its operand 1, so
EXPR_LOC_OR_HERE on either one will give input_location.
I guess we want a build_min_nt_loc function.
