    MATCH: Fix invalid signed boolean type usage

    This fixes the incorrect assumption that was done in
r14-3721-ge6bcf839894783,
    that being able to doing the negative after the conversion would be a v=
alid
thing
    but really it is not valid for boolean types.

    Bootstrapped and tested on x86_64-linux-gnu.

    gcc/ChangeLog:

            PR tree-optimization/112738
            * match.pd (`(nop_convert)-(convert)a`): Reject
            when the outer type is boolean.
