Change the `(zero_one ==/!= 0) ? y : z <op> y` patterns to use multiply rather than `(-zero_one) & z`
Since there is a pattern to convert `(-zero_one) & z` into `zero_one * z` already,
it is better if we don't do a secondary transformation. This reduces the extra
statements produced by match-and-simplify on the gimple level too.
gcc/ChangeLog:
* match.pd ((zero_one ==/!= 0) ? y : z <op> y): Use
multiply rather than negation/bit_and.
