    asan: Don't instrument .ABNORMAL_DISPATCHER [PR114743]

    .ABNORMAL_DISPATCHER is currently the only internal function with
    ECF_NORETURN, and asan likes to instrument ECF_NORETURN calls by adding
    some builtin call before them, which breaks the .ABNORMAL_DISPATCHER
    discovery added in gsi_safe_*.

    The following patch fixes asan not to instrument .ABNORMAL_DISPATCHER
    calls, like it doesn't instrument a couple of specific builtin calls
    as well.

            PR sanitizer/114743
            * asan.cc (maybe_instrument_call): Don't instrument calls to
            .ABNORMAL_DISPATCHER.

            * gcc.dg/asan/pr112709-2.c (freddy): New function from
            gcc.dg/ubsan/pr112709-2.c version of the test.
