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.
