[Bug middle-end/28042] optimizer (-O2) changes the semantics of my programs

Even better, if you remove the redundant parens, so that the program reads 

...
    if ((integerValue >= 0)
        && (integerValue >= -1073741824) && (integerValue < 1073741824)) {
...


then the optimizer generates code correctly! (How on earth can paren placement
affect code generation???)
