    Fix PR 110487: invalid signed boolean value

    This fixes the first part of this bug where `a ? -1 : 0`
    would cause a value of 1 into the signed boolean value.
    It fixes the problem by casting to an integer type of
    the same size/signedness before doing the negative and
    then casting to the type of expression.

    OK? Bootstrapped and tested on x86_64.

    gcc/ChangeLog:

            * match.pd (a?-1:0): Cast type an integer type
            rather the type before the negative.
            (a?0:-1): Likewise.=
