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.

* 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.
