[PATCH] Fix a typo in range_entry_cmp (PR tree-optimization/61686)

[Marek Polacek]

I don't really know this code, but this typo looks obvious enough.
Using if (p->high != NULL_TREE) ... else if (p->high != NULL_TREE)
couldn't be possibly desired, so use Q in the else branch, as in
the code slightly above.

Bootstrapped/regtested on x86_64-linux and ppc64-linux, ok for trunk?
