cmp_8 = -_2;
_3 = cmp_8 & a_6(D);
We convert that into:
_2 * a_6(D);
And then have:
_11 = _2 + -1;
_5 = b_7(D) & _11;
This could be convert into:
(_11 ^ 1) * b_7(D)
```

I should we already handle:
```
int f3(int a, int b)
{
int cmp = -(a > b);

With the patch (which only affects vectors), f becomes (a>b)?a:b. It should be
easy to add the corresponding transform to MAX_EXPR in match.pd.

I'd say generate a (vec_)cond_expr, not directly a max. That is, replace the
comparison with any truth_valued_p (hmm, that function probably stopped working
for vectors when all comparisons were wrapped in vec_
