    r600/sb: fix crash in fold_alu_op3

    fold_assoc() called from fold_alu_op3() can lower the number of src to 2,
    which then leads to an invalid access to n.src[2]->gvalue().
    This didn't seem to have caused much harm in the past, but on Fedora 28
    it will crash (presumably because -D_GLIBCXX_ASSERTIONS is used, although
    with libstdc++ 4.8.5 this didn't do anything, -D_GLIBCXX_DEBUG was
    needed to show the issue).

    An alternative fix would be to instead call fold_alu_op2() from within
    fold_assoc() when the number of src is reduced and return always TRUE
    from fold_assoc() in this case, with the only actual difference being
    the return value from fold_alu_op3() then. I'm not sure what the return
    value actually should be in this case (or whether it even can make a
    difference).
