    cgraph: Adjust verify_corresponds_to_fndecl [PR106061]

    IPA passes redirect some calls in what it determines to be unreachable code
    to builtin_decl_unreachable.  But that function returns sometimes
    builtin_decl_explicit (BUILT_IN_UNREACHABLE) (which was what GCC 12
    and earlier did always), or builtin_decl_explicit (BUILT_IN_TRAP)
    (e.g. for -funreachable-traps, -O0, -Og).
    Now the cgraph verification code has a code to verify cgraph edges
    and has there an exception for these redirections to BUILT_IN_UNREACHABLE,
    but doesn't have for BUILT_IN_TRAP, so e.g. the following testcase
    ICEs during that verification.

    The following patch just adds BUILT_IN_TRAP to those exceptions.

            * cgraph.cc (cgraph_edge::verify_corresponds_to_fndecl): Allow
            redirection of calls to __builtin_trap in addition to redirection
            to __builtin_unreachable.

            * gcc.dg/pr106061.c: New test.
