    [Committed] Fix tree-optimization/103152: Still one more -signed1bit is=
sue

    When I fixed PR 102622, I accidently left behind a TYPE_PRECISION
    check which I had there for checking before hand.  This check
    is not needed as the code will handle it correctly anyways.

    Committed as obvious after a bootstrap/test on x86_64-linux-gnu.

            PR tree-optimization/10352

    gcc/ChangeLog:

            * match.pd: Remove check of TYPE_PRECISION for
            the a?0:pow2 case.

    gcc/testsuite/ChangeLog:

            * gcc.c-torture/execute/pr10352-1.c: New test.=
