    c-family: fix attribute constructor ICE [PR90658]

    Here the C compiler crashes because a FUNCTION_DECL got into
    get_priority -> default_conversion, and the C FE's version of d_c
    specifically asserts that it doesn't get a FUNCTION_DECL.  All uses
    of default_conversion in c-attribs.cc are guarded by != IDENTIFIER_NODE
    && != FUNCTION_DECL, but get_priority was only checking IDENTIFIER_NODE.

            PR c/90658

    gcc/c-family/ChangeLog:

            * c-attribs.cc (get_priority): Check FUNCTION_DECL.

    gcc/testsuite/ChangeLog:

            * c-c++-common/attr-cdtor-1.c: New test.
