Untested fix. CAND_ADD can apparently be set even on c->cand_stmt which isn't
a addition (e.g. cast of the addition etc.), plus by just silently assuming
that if rhs1 isn't equal to c->base_expr, then rhs2 is, doesn't work in all
cases.
In particular, c->cand_stmt can be e.g. addition of two SSA_NAMEs where each
one of those adds in some part, not equal to c->base_expr.
