[Bug tree-optimization/19105] New: fold does not spot anti-range test

[nathan at gcc dot gnu dot org]

The attached test case shows two equivalent functions, unfortunately the
first is not optimized as best as the second.  Notice the only different is the
placement of some superfluous parentheses.

Death to fold-const!
