Add op for float max and min for x86.
The ops `Omaxf` and `Ominf` have the same semantics as `minsd` and
`maxsd` instruction, i.e. if both arguments are equal the second
argument is returned as well as for NaN.
The operations are the used in SelectOp to implement the built-in
function `__builtin_fmax` and `__builtin_fmin`.
