[PATCH 1/3] MATCH: Move `a ? one_zero : one_zero` matching after min/max matching

[Andrew Pinski via Gcc-patches]

In PR 106677, I noticed that on the trunk we were producing:
```
  _25 = SR.116_117 == 0;
  _27 = (unsigned char) _25;
  _32 = _27 | SR.116_117;
```
>From `SR.115_117 != 0 ? SR.115_117 : 1`
Rather than:
```
  _119 = MAX_EXPR <1, SR.115_117>;
```
Or (rather)
```
  _119 = SR.115_117 | 1;
```
Due to the order of the patterns.

OK? Bootstrapped and tested on x86_64-linux-gnu with no
regressions.

gcc/ChangeLog:

        * match.pd (`a ? one_zero : one_zero`): Move
        below detection of minmax.
