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.
