    MATCH: Fix zero_one_valued_p's convert pattern

    While working on PR 111972, I was getting a regression
    due to zero_one_valued_p matching a signed 1 bit integer
    when it came to convert. This patch fixes that by checking
    the outer type too.

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

    gcc/ChangeLog:

            * match.pd (zero_one_valued_p): For convert
            make sure type is not a signed 1-bit integer.
